Circular walk from Lesnewth to Tresparrett
  1. From Lesnewth church, follow the lane downhill to reach a track on the right signposted by a stone marker to Halamiling Farm and a public footpath sign. Walk down the track until you reach a gate.

    In much of Cornwall, many of the place names are based on words from the Celtic language. The following prefixes are common:

    • Tre - settlement or homestead
    • Lan - originally monastery but later used for an enclosure or church (this has been replaced with "St" in a number of cases)
    • Nans - valley (occasionally corrupted to "Lan" e.g. Lanteglos)
    • Pen - hill or headland
    • Pol - pond, lake or well, also cove or creek
    • Fenter - spring
  2. Go through the gate to Halamiling Farm. Follow the track down the Trebiffin Valley until a track departs to the left just before the garage.

    The steep Valency Valley acted as a funnel for the dramatic flash flood in 2004 that put Boscastle on (and nearly wiped it off) the map. Over 1.4 billion litres of rain fell in the course of 2 hours which is thought to have been caused by the Brown Willy effect, where the high tors on Bodmin Moor cause the repeated formation of rain clouds which blow along the prevailing wind and then dump their rain. Around 50 cars were swept into the harbour, the bridge was washed away and roads were submerged under 9ft of water. A total of 91 people were rescued in the largest peacetime rescue operation ever carried out in the UK.

  3. Bear left onto the gravel track indicated by the white arrow on the post. Follow this until it bends to go through a gateway.

    Halamiling was recorded in 1327 as Lamelyn which is thought to be a corruption of nansmelyn - the Cornish for "valley mill". The name gradually drifted further off the rails during Victorian times via "Allemelon" and "Hahamellin" to reach the current form.

  4. At the bend, bear right onto the grassy track and follow this to a waymarked kissing gate.

    Despite being called red campion, its flowers are most definitely pink - varying quite widely in shade from vibrant deep pinks to very pale. The colour is produced by red anthrocyanin compounds which are also responsible for red autumn leaves and red tinges on new growth in some plants as well as flower colours. In red campion, the intensity of the colour is controlled by a pair of genes and several other genes control the exact balance of anthrocyanin compounds within the petals. These are passed down the generations and so pale pink parents are likely to produce pale pink offspring.

    Insects are the most diverse group of organisms with around 900,000 known living species. This makes up 80% of all the world's known species. However it is thought that even today there are still more unknown species than known ones with estimates of the total number of insect species in the range 2 - 30 million.

  5. Go through the gate and bear right to reach a footbridge over the Valency river.

    The Ramblers Association and National Farmers Union suggest some "dos and don'ts" for walkers which we've collated with some info from the local Countryside Access Team.

    Do

    • Stop, look and listen on entering a field. Look out for any animals and watch how they are behaving, particularly bulls or cows with calves
    • Be prepared for farm animals to react to your presence, especially if you have a dog with you.
    • Try to avoid getting between cows and their calves.
    • Move quickly and quietly, and if possible walk around the herd.
    • Keep your dog close and under effective control on a lead around cows and sheep.
    • Remember to close gates behind you when walking through fields containing livestock.
    • If you and your dog feel threatened, work your way to the field boundary and quietly make your way to safety.
    • Report any dangerous incidents to the Cornwall Council Countryside Access Team - phone 0300 1234 202 for emergencies or for non-emergencies use the iWalk Cornwall app to report a footpath issue (via the menu next to the direction on the directions screen).

    Don't

    • If you are threatened by cattle, don't hang onto your dog: let it go to allow the dog to run to safety.
    • Don't put yourself at risk. Find another way around the cattle and rejoin the footpath as soon as possible.
    • Don't panic or run. Most cattle will stop before they reach you. If they follow, just walk on quietly.
  6. Cross the footbridge and head straight across towards the gap in the hedge ahead leading to a gateway.

    Streams from the marshes of the Otterham Downs give rise to the River Valency which is then fed by five more rivers on its way to Boscastle. The name "Valency" has been explained as a corruption of the Cornish Melinjy (i.e. "Melin chy" = Mill-house) from the mill which existed in Boscastle in mediaeval times.

  7. Go through the gap and gateway then follow the right hedge to the top of the field to reach a gateway on the right with a signpost for New Mill.

    It is probable that the original patron of St Juliot, Lanteglos church and Tintagel Castle's chapel (all dedicated to St Julitta) was St Juliana, mentioned in the 12th-century Hartland list of the children of Brychan. Other than that mention, little is known - even the gender is a bit sketchy, with the picture of St Julitta in Tintagel Church depicting a man, but many assume from the name that the saint was female.

  8. Turn right through the gateway and head to the right of the telegraph pole in the hedge on the opposite side of the field to a stone stile.

    Brychan was a legendary Celtic king (originally born in Ireland) who ruled over Breconshire in South Wales and was viewed as the father of the Celtic saints.

    Several mediaeval manuscripts state that he was married three times but the numbers of children vary from 12 to 63 with 24 being the most commonly reported number. There is also little agreement in the lists of names between Cornish and Welsh manuscripts. It is thought that the list of his children may have grown over time as more people claimed themselves or their local saint to be descended from what was seen as the holy family.

  9. Cross the stile and turn right. Follow the right hedge past the gateway to a stile in the far corner of the field.

    To discourage herbivores from eating them, nettles leaves have tiny spikes which inject a stinging venom. The myth that nettle stings are caused by acid is one that needs debunking as the formic acid in nettle venom is at a concentration that is too low to cause a sting. It is actually a combination of neurotransmitters (histamine, serotonin and acetylcholine) in the venom which causes skin irritation. The most effective relief is likely to be from an antihistamine cream but only if applied quickly enough.

  10. Cross the stile and keep to the right hedge through this field to a stile in the bottom right hand corner.

    Swallows have evolved a long slender body and pointed wings that makes their flight more than twice as efficient as other birds of a similar size. In flight, swallows can reach 35 mph which is particularly impressive given they weigh only 20 grams.

    Scientists have found that cows tend to lie down when the weather is cool but stand up when it's hot to improve air circulation and regulate their body temperature. The folklore about cows lying down being a sign of rain might well be due to the cold fronts causing precipitation being reflected in the "cow thermometer". Cows also lie down to sleep but they only sleep for about 4 hours a day.

  11. Cross the stile and bear left to a metal pedestrian gate. Go through this and up the stone steps then continue to the church door.

    St Juliot's Church is situated in a beautiful location with its door facing out across the Valency valley. Formerly there was a chapel on the site, dating back to mediaeval times. This was later replaced with a church with a tower dating from the 14th Century and south aisle from the 15th Century. The church was renovated by the author Thomas Hardy. The tower was in such a state of collapse that it needed to be entirely rebuilt, but the 15th Century aisle survived and now forms the nave and chancel.

  12. Walk around the church to the right to reach the churchyard gate.

    Scholars speculate that the Celtic Cross (a crucifix with a circular ring) developed from the sun cross (a cross inside a circle), a common symbol in artefacts of Prehistoric Europe, particularly during the Neolithic to Bronze Age periods. When Christianity came to the Celtic regions, Christians extended the bottom spoke of this familiar symbol, to remind them of the cross on which their new Saviour was crucified.

  13. Go through the gate and turn left onto the lane. Follow the lane until you reach a junction signposted to Boscastle.

    The vetches are a family of wildflowers that is a sub-group within the pea and bean family. Their pretty purple flowers are quite like mini sweetpea flowers. The leaves are also very distinctive, organised in a neat row either side of the stem. Common vetch is a wildflower but is also sown by farmers in some grazing fields to improve the nutrition for ruminants and to introduce more nitrogen into the soil.

    Tarmac was discovered by accident in 1901 when a barrel of tar fell and burst open on a road and then waste slag from a nearby furnace was used to cover up the mess. The resulting smooth surface was noticed by a surveyor for Nottingham County who patented the idea, formed the Tar Macadam Syndicate and registered Tarmac as a trademark.

    This has been adopted into the English language initially as tarmacadam and increasingly now as just tarmac. When used as an adjective it gains an extra "k" (i.e. tarmacked).

  14. At the junction, turn right through the gate to pass the barns and gates on the right. Then follow the right hedge to a gate.

    A Lunula - a gold ornament of the Bronze Age, dating from about 2000BC - was found in the 1800s by some labourers who were working in a field at St Juliot. It is now in the Truro museum. Only 3 others have been found in Cornwall - two at Harlyn Bay near Padstow and one at Penwith.

    Lunulae were neck ornaments and have been found dating from the Late Neolithic to the Early Bronze Age. Four have been found in Cornwall and are all made of very thin gold. The crescent shape of lunulae is thought to indicate a symbolic meaning, representing the crescent horns of the moon, and they may thus have been objects of ceremonial significance. A number of similar lunulae have been found in Ireland and also Brittany. It is thought the four found in Cornwall were all made from Irish gold and manufactured either in Ireland or Brittany and brought along the trade route between the two passing through Cornwall.

  15. Go through the gate and follow the right hedge/fence to a stile in the right hand corner.

    Cows eat about 10kg of grass a day and a dairy cow produces around 50 pints a day on average rising to around 100 pints at their peak.

  16. Cross the stile (take care of the overhanging branches) and follow the right hedge to reach a tarmacked track on the far side.

    Clover is a native plant and a member of the legume (pea and bean) family. It is also sown as a fodder crop and as "green manure" as it improves soil fertility. The two most common species are known simply as white clover and red clover, based on the colour of their flowers, with the latter generally being a slightly larger plant. Red clover leaves also have a white V shape.

  17. Join the track and bear right to follow it past West Park and East Park and around a bend to the left until you reach a fork in the track in front of Over Park.

    Park is the Cornish word for "field" and during mediaeval times the words, over and nether were used to denote "higher" and "lower".

  18. At the fork, keep left and pass the tarmac driveway on the right. Follow the track through the metal gate and then bear right at the next fork into a field. Continue on the track to where it bends to the right and a gap in the electric fence (opened using the spring-loaded wire) enables access to the field on the left.

    Through the gateway to the left is a circular mound on the far side of the field. This earthwork is the remains of an Iron Age settlement.

  19. Bear left from the track through the gap in the electric fence and cross the field to reach another gap in the electric fence on the far side.
  20. Pass through the gap in the electric fence onto the track then turn right (downhill) and follow this to a junction of tracks. From the junction, go through the metal gate on your left into the field then follow the right hedge to a metal gate in the far right corner.

    Where an electric fence crosses a footpath, it should either be covered by an insulating sheath (e.g. on stiles) or there should be a section that unclips with insulating plastic handles to allow access through the fence. Ensure that you re-clip this on passing through so animals cannot escape. The connecting cord/spring between the handles is often conducting so avoid touching this and be aware of any dangling rucksack straps.

  21. Go through the gate and follow the right hedge through a gap in another electric fence to the gate in the far right corner.

    The fields are hedged with blackthorn.

    The name "blackthorn" is just a general reference to the dark colour of the bark, rather than anything specific to do with the thorns which are not any darker than the rest of the wood. It's primarily a comparison with hawthorn where the bark is lighter (in fact hawthorn is also known as "white thorn" despite not having white thorns). Just to confuse things further, the flowers of blackthorn are whiter than hawthorn!

  22. Go through the gate and continue along the right hedge through a gap in another electric fence to the gate in the far right corner.

    Pineapple weed is related to chamomile and is consequently also known as false chamomile. Unlike chamomile, it doesn't have white flowers - its flowers consisting of little yellow balls are therefore quite distinctive. Even more so is the fruity pineapple-like scent when is trodden on or squeezed.

    Pineapple weed leaves and flowers can be eaten in salads or dried to make tea. The flower heads can also be used to make a syrup by first infusing the flower heads in simmering water then straining off the liquid and adding sugar to this.

    To make sloe gin, wash your sloes and prick each one with a fork. Put your pricked sloes into a container with a lid and a suitably large neck so you can pour them out later - 4 litre milk containers, washed out very thoroughly, are ideal. Fill about 80% of the way to the top with the cheapest gin you can find (don't waste your money on expensive gin as you are about to transform it into something altogether different). Fill the remaining 20% with white sugar (it looks a lot but sloes are incredibly bitter and this offsets it) and leave to infuse for a few months; agitate gently occasionally to help the sugar dissolve without mashing the sloes which would make your drink cloudy. Drain the beautiful red liquid into a decanter to admire before consumption.

    The expression "Blackthorn Winter" is a rural expression for a final cold snap in late March or early April when the blackthorn is in flower. It was generally used in the context of not getting too carried away (e.g. planting crops) if there was a warm week in early March as more frosts may still be yet to come.

  23. Go through the gate and continue along the right hedge to a gateway in the far right corner.

    Once you've made your sloe gin, don't throw away your gin-soaked sloes! Instead buy some cheap sweet "cooking" cider (the kind that comes in 2 litre plastic bottles preferably with words like "value", "basic" or "economy"; do not commit heresy and waste good quality drinking cider) and replace the gin with this. Ensure your lid is on tight so your cider doesn't lose its fizz. Leave to infuse for a few more months for your cider to become osmotically fortified. The resulting delightful drink is known as "slider" (after several glasses anyway). Based on "experience", small-sized glasses are recommended.

    Due to blackthorn wood's toughness, it was used to make tool handles, walking sticks and as a traditional Celtic weapon for clubbing people to death! It is still regarded as the ultimate wood for making walking sticks. Once cut and trimmed, the wood needs to be dried for at least a year (often several) which allows moisture to escape and the wood to shrink and harden.

  24. Go through the gateway and follow the right hedge to a metal gate with a road sign ahead.

    The settlement of Tresparrett dates back to mediaeval times and was known originally as Paruet or Rosperuet. In 1086 there were 6 households recorded here.

  25. Go through the gate and walk to the signpost then join the lane ahead signposted to Marshgate. Follow this to a junction on the right beside the phone box.

    The red telephone box was the result of a competition in 1924 to design a more aesthetically-pleasing telephone kiosk that would be acceptable to the London Metropolitan Boroughs who weren't impressed by the Post Office's first 1921 model made from concrete. Three subsequent versions were used mostly in London. The final design was created in 1935 to commemorate the jubilee of George V and was deployed widely across the country.

    The bright red telephone box was initially not well-received and the Post Office was forced to use an alternative colour scheme (grey with red glazing bars) for areas of natural beauty. Ironically, many of the telephone boxes preserved in these areas have since been painted - the now iconic - red.

  26. Turn right in front of the phone box and follow the road down the hill and around the bend to the left to reach Old Smithy Cottage on the left with a track departing to the right.
  27. Turn right onto the track marked with the public footpath sign and follow it to where a path leads off from the left just before it ends at a gate.

    A little further along the lane is the Horseshoe Inn, if you want to stop for refreshment.

    The Horseshoe Inn, in Tresparrett, has only been a pub since 1977. Prior to that, it was a house & blacksmiths (hence the name) which were knocked together into one to become the village shop. It took many years to obtain a license to turn it into a pub due to opposition from some villagers. The pub is only open all day on Sundays during the summer, otherwise it opens at 12 PM and closes at 3 PM so bear this in mind if you are planning on stopping there.

  28. At the end of the track, bear left down a path to the bottom of the valley to a footbridge.

    The stream is a tributary of the River Valency which rises at Marshgate (hence the name) and joins the main river roughly a quarter of a mile downstream from here. The point where the route first crossed the river is a about a mile below this confluence (so has the combined flow).

  29. Cross the footbridge and stile, and continue ahead up the field to an opening in the right hedge approximately 50m from the top corner of the field, just to the right of a large tree.

    The dandelion-like flowers along the coast are most likely to be catsear, also known as false dandelion. Catsear is very salt tolerant, not only growing along the coast but actually in sand dunes. The easiest way to recognise it is by the hairy leaves, hence the name. If you can cope with the texture, the leaves are edible and are much less bitter than dandelion leaves.

    Another way to tell them apart is when they are flowering. Although dandelion flowers over quite a long period, the most profuse flowering is in April and May whereas catsear's intense flowering period is in late June and through July. Catsear has neater flowers than dandelion with squarer edges to the petals (but still toothed). The stems supporting the flowers are also solid, in contrast with the hollow stem of the dandelion.

    During Victorian times and earlier, small amounts of land in Cornwall were measured by the goad - a unit of nine feet in length, derived from the name of the staff used to drive oxen.

    An English acre was less generous (at 43,560 square feet) than a Cornish acre (51,840 square feet). Although both were defined as 160 smaller land units, the English equivalent to the Cornish goad was a perch but this was 5.5 yards (16.5 ft) rather than the two-goad length used in Cornwall of 6 yards (18 ft). It is thought that the reason the perch ended up as a non-round number of feet is that it was originally measured from 20 averaged-sized human feet in Saxon times when nutrition wasn't great.

  30. Go through the opening and cross the field to a gateway in the far hedge approximately 10 metres down from the top hedge.

    If there are sheep in the field and you have a dog, make sure it's securely on its lead (sheep are prone to panic and injuring themselves even if a dog is just being inquisitive). If the sheep start bleating, this means they are scared and they are liable to panic.

    If there are pregnant sheep in the field, be particularly sensitive as a scare can cause a miscarriage. If there are sheep in the field with lambs, avoid approaching them closely, making loud noises or walking between a lamb and its mother, as you may provoke the mother to defend her young.

    Sheep may look cute but if provoked they can cause serious injury (hence the verb "to ram"). Generally, the best plan is to walk quietly along the hedges and they will move away or ignore you.

  31. Go straight ahead to the waymarked pedestrian gate and go through this to reach a track. Turn right onto the track to reach a fork. At the fork, follow the left track uphill for a short distance to a junction.

    There are chicken coups beside the track which are sometimes open to allow free-ranging.

    Chickens are descended from junglefowl and those in Britain came originally from India. They evolved the ability to lay large numbers of eggs to take advantage of gluts of food that occur in their native forests. It is thought they were introduced to Britain by Iron Age tribes who bred them for fighting rather than meat and cockfighting remained Britain's national sport until 1835. During the mediaeval period, more placid forms of chicken were bred that were less hazardous to farm but it wasn't until the 17th Century that chickens and eggs were farmed on a mass scale. In Britain, over 10 billion eggs are now consumed every year.

  32. At the junction, turn right down the track, then immediately left before the barn to reach the left of two gates.

    The settlement of Trevilla is thought to date from early mediaeval times and there are records from 1284. It is thought to be based on an Old English (rather than Celtic) personal name, reflecting the proximity to the Devon border which was along the River Ottery (not Tamar) during mediaeval times.

    One of the buildings further downhill (on private land and not visible from the footpath) has the remains of an old waterwheel. This was fed from the pond (which can be seen from the track) via a sluice and leat leading downhill to the wheel.

  33. Go through the waymarked gate and follow the right hedge to an opening in the far hedge.

    From Tudor times onward, the majority of farming in Cornwall was based around rearing livestock with dairy cattle being predominant. This is reflected in traditional Cornish dairy produce including clotted cream and, later, ice cream and in the North Cornwall dialect where the pejorative for "farmer" was a fairly graphical description of the act of milking before the introduction of milking machines which rhymed with "bit fuller".

  34. Go through the opening and follow the right hedge to a waymarked opening.

    The salt-laden breeze coming off the sea dries out leaf buds and inhibits growth so the plants end up growing most vigorously in the lee of the wind. In the direction facing the prevailing wind, the growth is therefore more compact and stunted whereas in the lee of the wind, the branches are much more straggly. The result is that the trees appear to point away from the prevailing wind. Where there are no obstacles interfering with the wind direction, the shape of the trees can be used as a compass. Prevailing winds come from the southwest, so in general, trees in Cornwall point northeast.

  35. Go through the opening and bear left to locate a gap between the gorse bushes leading down the bank. Make your way down the bank to reach a path running along the bottom of the bank.

    Gorse is present as two species along the Atlantic coast and size is the easiest way to tell them apart: Common Gorse bushes are up to 10ft tall whereas Western Gorse is more of a mat - less than 1ft tall. Common Gorse flowers in spring whereas Western Gorse flowers in late summer - early autumn.

  36. Turn left onto the path along the bottom of the bank. Follow the path until you can see a footbridge on the right, then follow the path down to the bridge.
  37. Cross the bridge and head across the field to another wooden footbridge.

    The stream is the upper reaches of the River Valency. Its source is beside the A39 at Trewannion Gate near Otterham Station. The second bridge is over a stream which rises from a spring at Helsett Farm.

  38. Cross the bridge and follow the path to a waymark. Bear left at the waymark and follow the path to a gate into a field.

    To make blackberry wine, combine 2kg blackberries + 4 litres of boiling water in a plastic container with a lid. Once the water has cooled to lukewarm, mash blackberries and add red wine yeast and pectic enzyme (blackberries contain pectin so this is needed to stop the wine being cloudy). Cover for 4-5 days then strain through muslin.

    Transfer the liquid to a demijohn and add 1kg of sugar. Top up with a little more water to make it up to a gallon. After fermentation, the wine should clear by itself; in the unlikely event that it doesn't, use some finings. Rack off from the sediment and bottle; it's worth allowing the wine a year or two to mature as it massively improves with age. As a variation, you can add 500g of elderberries and increase the sugar content for a more port-like wine which will need a couple of years longer for the elderberry tannins to mellow out.

    The bramble is a member of the rose family and there are over 320 species of bramble in the UK. This is a big part of why not all blackberries ripen at the same time, and vary in size and flavour.

  39. Go through the gate and continue ahead to another metal gate in the top-right corner of the field.

    The standing stone in the centre of the field is more likely to be a cattle rubbing stone rather than a prehistoric structure. It is not recorded as an ancient monument.

    In pre-industrial times, cattle were allowed to roam over quite large areas and could therefore find a suitable tree to relieve an itch. In the Victorian period, farming became more intensive and cattle were moved into enclosed fields. It was quickly discovered that an itchy cow could wreak havoc with walls and fences so dedicated rubbing stones were positioned in the centre of some fields to minimise cow damage. In some cases, new stones were quarried specifically for the purpose and others, existing prehistoric standing stones or even Celtic crosses were unceremoniously re-used.

  40. Go through the gate ahead and follow the fence on the right to a stile over the fence.

    If you are crossing a field in which there are horses:

    • Do not approach horses if they have foals, make loud noises nor walk between a foal and its mother as you may provoke the mother to defend her young. Generally the best plan is to walk along the hedges.
    • Horses will often approach you as they are used to human contact. If horses approach you, do not run away as this will encourage them to chase you. If you are uncomfortable with their proximity, calmly walk away.
    • Do not feed the horses with sweets or otherwise. Some food which is harmless to humans can be deadly to horses.
    • If you have a dog, keep it under close control in a visible but safe place, and as still and quiet as possible.
  41. Cross the stile and turn left to follow the fence on your left then bear right as you approach the hedge to the ladder stile to the left of the gate.

    Horses are related to tapirs and rhinoceroses. Unlike cows and sheep which have an area before their stomach (rumen) to process cellulose, horses and rhinos have a large pouch at the start of their large intestine where bacteria break down cellulose into digestible sugars.

  42. Cross the ladder stile, then go through the gate on the right and turn left to follow along the hedge, keeping it on your left to reach a pair of metal gates.
  43. Turn left through the gates and follow the track to a waymarked pedestrian gate on the right.

    Water pepper and lady's thumb grow in the damp ground along the track.

    Lady's thumb, also known as "redshank", grows on moist, disturbed ground often along field edges and tracks. It is related to water pepper and has similar long leaves but the lady's thumb leaves have a dark blotch (hence the thumbprint basis of the name). Its flowers are also in bigger clusters of pink rather than the puny white strand that water pepper produces. It is edible but without the chilli-like heat of water pepper (which provides a more memorable way to tell them apart).

    The plant has a plethora of local names in different parts of the UK but East Anglia deserves a mention for its baffling "saucy alice" and - an alternative suggestion for how the leaves got their markings - "devil's arse-wipe".

    The trees along the hedges provide perches for crows.

    The word crow is from the Old English crawe. Since this sounds a lot like the noise the bird makes, there is a misconception that the Old English is directly derived from this. In fact the word is far older. It's related the the Old Saxon kraia and can be traced back further to a Proto-Indo-European word from the late Neolithic period which is thought to mean "to call hoarsely".

  44. Go through the gate on the right into a garden. Keep left around the garden to pass the house and go up the slate steps to the metal gates.

    The settlement of Helsett was recorded in 1280 as Helliset but the origin of the name isn't clear. A manor was recorded here in the 15th Century so the name could possibly be based on hen-lys which is Cornish for "old court".

  45. Go through the metal gates and turn right onto the track. Follow the track until it ends at a T-junction.
  46. At the junction, turn left onto the lane and follow it a short distance to the Well House sign, then bear right onto the track along the hedge to the gate indicated by the Public Footpath sign.
  47. Go through the gate and follow the left hedge to a stone stile.

    As one would expect, Well House is located beside a spring. Another spring rises in the field, hence all the reeds.

    Wetlands act as sponges, storing and gradually releasing water which helps to prevent floods and buffer river levels during dry periods. Sediment and nutrients washed off the land by rainwater are absorbed by the wetland plants, feeding the wetland ecosystem but also filtering and cleaning the water before it enters rivers.

  48. Cross the stile (or go through the gate if open) and follow the right hedge to a stile in the far corner.

    Lesnewth is a small hamlet and civil parish situated two miles east of Boscastle. The name for Lesnewth in Cornish was Lysnowydh which means "New Court", which is a chieftan's estate. The farmhouse of Penpol dates back over 400 years, although there is believed to have been a settlement in this area for over 1000 years.

  49. Cross the stile and the one opposite to reach a lane. Turn right and follow the lane to return to the starting point of the walk.

    St Michael & All Angels Church in Lesnewth is in a lovely location, just next to a deep-sided stream, marked by an ancient Celtic wayside cross. The original Saxon church was said to be built here in the dip to hide it from marauding Vikings at sea, but they found and pillaged it nonetheless. Sadly, little remains of the Norman church that followed; the present church is mostly Victorian, dominated by an impressively tall 15th century tower. On one of the walls inside is a nicely inscribed slate memorial with a carved coat of arms.

The remains of a flat axe from the early Bronze Age was discovered in Lesnewth. The surface of the bronze is decorated with a rain pattern. It is now on display at the Royal Cornwall Museum in Truro.

The horse chestnut tree was introduced to Britain during Tudor times. Mature horse chestnut trees grow up to 40 metres tall and can live for up to 300 years. The association of conker trees with horses may be due to the horseshoe (complete with nail holes) shape of the leaf scars on the twigs.

Due to the name of the tree, there are stories that conkers were fed to horses as a stimulant, to make their coat shine or to cure coughs. However horse chestnuts contain a chemical compound - aesculin - which is poisonous to horses. It is also poisonous to dogs so they should not be allowed to chew the nuts.

The Vikings used crushed conkers to make soap as they contain saponins. As fresh conkers dry out, the saponins are released and scientists have found these repel moths. However no evidence has been found that they repel spiders despite many people believing this to be the case.

The game of conkers was first recorded on the Isle of Wight in 1848, but similar games were played in Britain and Ireland with hazelnuts or even snail shells before this. In recent years, many schoolchildren have become disinterested in playing conkers, preferring electronic gadgets that simulate the game by catapulting birds rather than horse chestnuts. However there has been a surge in interest from adults who would prefer to physically bash something, preferably less expensive than an iPhone. The World Conker Championship has been held in England since 1965 and now attracts competitors from all over the world.
