St Just-in-Roseland to Messack Point circular walk
  1. Turn right out of the car park onto the road and immediately right through the churchyard gate. Then bear left down the concrete path and make your way through the churchyard to the church (keeping left over the wooden bridge and left again after you pass the well). Bear right at the church to an arch (lychgate) signposted to the holy well.

    St Just In Roseland Church is based on a 13th Century building that was remodelled in the 14th and 15th Centuries and then reworked fairly heavily in a 19th Century restoration.

    During Victorian times, the area around the church was landscaped into gardens using semi-tropical species that are able to survive in the mild climate beside the river. The granite blocks alongside the path to the church are inscribed with quotations from the Bible.

  2. When you reach the arch signposted to the Holy Well, turn right to go through it. Follow the path along the edge of the creek, past the path to the holy well and continue to reach a waymark.

    Before Christianity, the Pagan Celtic people of Cornwall worshipped wonders of the natural world. Where clean, drinkable water welled up from the ground in a spring, this was seen as pretty awesome. The sites were seen as portals to another world, and is why fairies are often associated with springs. Where the springwater dissolved minerals, for specific conditions (e.g. deficiency in a mineral) or where the minerals present had antibacterial/fungal properties, the water appeared to have healing powers.

  3. Keep left at the waymark and follow the path, passing over a stile, to reach a gate.

    There are two types of ivy leaf. Those on creeping stems are the classic ivy leaf shape with 3-5 triangular lobes - they grow towards shade to find a tree to climb up. However, more mature ivy plants grow aerial shoots with a completely different (teardrop) leaf shape. These are the shoots that bear the flowers and fruits and are typically located in a sunny spot such as on an upright ivy bush or top of a rock face. The reason for the different shapes is that the larger, multi-lobed leaves are able to catch more light in shady areas whereas the smaller, stouter leaves are more resistant to drying out.

  4. Go through the gate and follow the remainder of the path then cross the driveway to the path to the left of the building opposite. Follow the path to a stile.

    The bright green heart-shaped leaves along the path are winter heliotrope.

    During winter, from November to March, winter heliotrope is visible along the edges of roads and paths as carpets of rounded heart-shaped leaves.

    The leaf shape of winter heliotrope is similar to its close relative butterbur, but the leaf edges are more rounded than butterbur and the leaves are evergreen whereas butterbur puts up flowers before it has any leaves. Both plants spread via rhizomes (underground stems) and their broad leaves can crowd out other plants making them potentially invasive.

  5. Cross the stile and cross over the track to the narrow path. Then continue ahead on this to reach a gateway into a field.

    Betony is a grassland herb, common on the coast, with pretty purple anthers that stick out from the plant. The name is derived from the ancient Celtic words bew (meaning head) and ton (meaning good) as it was used as a cure for headaches. From Roman times onward, it was believed to be a cure for a number of things (the Romans listed 47!) including drunkenness. Even as late as the 1800s, Richard E. Banks stated that you should "Eat betony or the powder thereof and you cannot be drunken that day" and John Gerard (1597) said that "It maketh a man to pisse well". Betony was also used to ward away evil spirits (hence it is planted in a number of churchyards) and also to make a dark yellow dye for wool.

    Cornwall bounces by around 4 inches every time the tide goes in and out. As the tide rises, the extra weight of water on the continental shelf deforms the Earth's crust; as the tide goes out, it springs back. The tidal range is greatest on the southwestern side of the British Isles and so Cornwall is one of the bounciest places in Britain.

  6. Go through the gateway and follow the path along the left hedge of the field to reach a gateway in the far corner.

    During the summer, the wildflowers in the meadow attract butterflies including the Common Blue and Yellow Brimstone.

    Exactly why butterflies were associated with butter is a bit of a mystery. One theory is that they were seen hovering over pails of milk and thought to be stealing or protecting the butter. Another is that the yellow brimstone was the species for which this name was first devised.

    The older an oak tree becomes, the more acorns it produces. A 70-80 year old tree can produce thousands. Acorns are high in carbohydrates and as well as being a staple food for squirrels, they are also a really important food for deer and make up a quarter of their diet in the autumn.

    Lichens often grow on sick or dying trees so some gardeners assume that the lichen might be harming the tree. In fact, it's purely because these trees have fewer leaves so there is more light available for the algae inside the fungus to photosynthesise. It's too dark under many healthy trees for the lichen to grow.

  7. Go through the gateway and follow the path over a concrete walkway and stile. Make your way into the field and follow the left hedge to a gap into the adjoining field.

    Holly has separate male and female plants, so not all holly bushes produce berries - only female plants. In less biologically-enlightened Pagan times, holly was thought to be a male plant (the spikes symbolising aggression) whereas ivy was regarded as a female plant (symbolising attachment). The Christmas Carol "The Holly and the Ivy" is thought originally to derive from Pagan fertility myths onto which Christian symbolism has subsequently been added.

  8. Go through the gap and continue ahead to meet the line of trees on the left. Follow along the trees to a gate in the far hedge.

    Some of the smaller trees along the left hedge are hazel.

    Hazelnuts can be found beneath the trees in September and October and are a favourite with squirrels so you'll need to forage those that haven't already been nibbled. Once harvested, the nuts need to be dried before shelling and eating. Wash and dry the nuts first to reduce the chance of them going mouldy. Then lay them out on something where the air can circulate and dry them for 2-4 weeks. An airing cupboard is a good place. You can tell that they are ready when the nuts rattle in their shells. Once shelled, the nuts can be stored in a fridge or even frozen for a couple of years.

    Hazel is one of the smaller native trees, reaching only 20ft. When allowed to mature, the tree lives for about 70 years.

  9. Go through the gate and follow along the left hedge. Pass two pedestrian gates (these lead down to the shoreline) until you reach a third with a green waymark.

    In autumn, sloes are often plentiful and can be used to flavour gin, sherry and cider. The berries can be harvested from September until nearly Christmas although more tend to shrivel as the autumn advances. Traditionalists say that you should wait until the first frosts in late November when the sloes are less bitter. This is because freezing breaks down the bitter tannins. Therefore you can pick your sloes in September before they go too wrinkly and then pop them in the freezer to achieve the same thing.

    Buzzards are not quiet birds! Their long, loud "pieeuuu" call can be often be the first thing to give away their presence and is one of the easiest bird calls to remember. It is thought that the original Latin word for buzzard was probably an onomatopoeia (i.e. an imitation of the bird's call) within the constraints of what was deemed an acceptable Latin word (suggesting "pieeuuu" would probably have resulted in being fed to the lions!).

  10. Go through the gate and follow the path over a pair of footbridges to a gate into a field.

    Despite their native habitat being woodland, wood pigeons are able to thrive wherever there is food. They have fared better than most birds with intensively-farmed crops and are particularly fond of oil seed rape. They are able to hoover up food quickly (up to 100 pecks per minute) and stuff large amounts into their crop (e.g. around 150 acorns!). They then digest this overnight.

  11. Go through the gate and head towards the farm gate in the top-right corner of the field, but stop short at a gap in the right hedge with a waymark in it.

    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.

  12. Go through the gap and then through the gate to the left of the waymark. Then follow the left hedge all the way along the large field to a pedestrian gate on the far side.

    Sheep were one of the first animals to be domesticated by humans. Domestication is thought to have started roughly around 12,000 years ago in Mesopotamia. The first sheep weren't woolly and were used for meat, milk and their (woolless) hides which were sometimes tanned to make leather. Woolly sheep were bred about 4,000 years later in Iran.

  13. Go through the gate and cross the driveway to a gate opposite signposted "Messack Point Circular Walk". Go through the gate and follow along the left hedge to a gate in the far corner.

    Although there is fresh water flowing down the rivers, as the tide begins to rise, the majority of the water in the creeks is seawater. Therefore on rocky outcrops such as Messack Point, rockpools containing seawater are formed by the ebbing tide which support saltwater species such as anemones.

    There are two types of anemone that you're likely to encounter on Cornish beaches. The most common are those that look like red blobs out of the water, known as beadlet anemones; in the water they open into a crown of tentacles. The little blue beads around the edge that give them their name are fighting tentacles, used to beat up rival anemones and chase them out of their territory (they can move around on the rocks albeit very slowly). The other species is the larger, green-and-purple snakelocks anemone which has tentacles that contain a fluorescent green algae which glows under UV light (should you own a battery-powered UV lamp and be on the beach at night). Anemones are very long-lived, often reaching 60-80 years and more. They do not age and have the potential to live indefinitely if they are not eaten by predators.

  14. Go through the pedestrian gate on the right of the gate, then bear left from the metal sign to stay in the field and walk downhill parallel to the wall on the right. Continue to the bottom of the field to reach a gate.

    As you descend the hill, there are views across Carrick Roads to Falmouth.

    Falmouth harbour is one of the largest natural harbours in the world and the deepest in Western Europe. The large waterway of Carrick Roads, forming the junction of seven estuaries, was created after the Ice Age from an ancient valley which flooded with the rising sea levels as the ice caps melted.

  15. Go through the gate and descend to some large trees, then turn right and follow the path parallel to the creek. Follow the path through the woods, eventually crossing a bridge and then climbing to a gate into a field.

    Beneath the trees, a path leads down onto the rock platform on the point. From here there are panoramic views back up St Just Creek to the left and along Carrick Roads to the right.

  16. Go through the gate and follow the right hedge past a pedestrian gate for the Messack Point and continue following the right hedge (in the direction indicated for Turnaware) until you reach a waymark and wooden pedestrian gate in the corner of the 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 hedge on the right contains hawthorn trees.

    The genus name for hawthorn - Crataegus - is derived from krátys the Greek word for "hard" or "strong". Hawthorn wood is fine-grained, dense and most definitely hard. It has traditionally been used for things that benefit from these properties such as wooden mallets, the teeth of rakes and cogs for mill wheels.

  17. At the waymark, go through the gate on the right and turn left to follow the path between the hedge and fence to another gate. Go through this and follow the path between the electric fence and hedge to reach a gate on the far side of the field.

    Electric fences are typically powered from a low voltage source such as a car battery which charges a capacitor to release a periodic pulse of high voltage electricity. This is often audible as a quiet "crack" which is a good indicator that a fence is powered. As with the high-voltage shock caused by static electricity, the current is not high enough to cause serious injury but touching an electric fence is nevertheless unpleasant. If you are answering the call of nature in the vicinity of an electric fence, be mindful of the conductivity of electrolyte solutions!

  18. Go through the gate and follow the path through the bushes to a gate.

    Apple pips contain contain a compound called amygdalin, which is cyanide bonded with sugar. In the gut this is converted to hydrogen cyanide. If you accidentally swallow a couple then don't panic: you'd need to chew and swallow hundreds of apple pips to get a fatal dose of cyanide.

    The settlement of Messack was first recorded in the early 13th Century as Maisoch. The name is based on the Cornish word for "open fields". The farm has the remains of a mediaeval field system which would have originally been long, narrow strip fields. The edges between many of the strips have been removed to create larger fields.

  19. Go through the gate and turn right to cross the lane to a waymarked gate on the opposite side of the lane. Go through the gate into the field and follow the left hedge to the second of two waymarks beside the bushes.

    In mediaeval times, the Anglo-Saxon "stitch meal" technique was adopted in some parts of Cornwall. This involved dividing arable and meadow land into long strips called "stitches". Villagers would be allocated a (usually disconnected) set of strips so that the "best" fields were shared around as evenly as possible. The long, thin shape was ideal for ploughing with oxen. A typical stitch was one furlong in length and one acre in area, which could be ploughed by a team of oxen in a day.

    A similar, but not identical, system of strip fields known as "burgage" plots was also used in mediaeval times but these were associated with a row of houses along a road in a settlement. The burgage plots were effectively very long, thin back gardens that also contained about an acre of cultivatable land.

  20. At the waymark, continue ahead to pass the brambles and gorse then bear left to descend to the path beneath the trees. Follow this through a gate and continue until you emerge into a field.

    Compared to red squirrels, grey squirrels are able to eat a wider diet (including acorns), are larger so can survive colder winters, and are better able to survive in the fragmented habitats created by urbanisation. They are also thought to be carriers of a squirrel pox virus which they usually recover from but has been fatal to red squirrels, although red squirrels are now also developing some immunity.

  21. Continue ahead to cross the field to the bottom corner and reach the stile and footpath sign that you encountered earlier. Cross the stile and follow the walkway back to the gateway into the field.

    Dragonflies were some of the first winged insects to evolve, around 300 million years ago in the "age of amphibians" before the dinosaurs. Fossils of early dragonflies have been found with wingspans of up to two feet across.

    The National Trust is the largest owner of farms in the UK. It has around 2,000 tenants and over 600,000 acres of land. It has been calculated that 43% of all the rainwater in England and Wales drains through National Trust land.

  22. Go through the gateway and keep right to retrace your steps, following the path over a stile and back to the driveway.

    Grasshoppers jump by using the stiff cuticle within their legs which functions a bit like a longbow. Muscles gradually build up stored energy by bending the elastic structures in the leg over quite a long period (around half a second) and then this is released suddenly.

    The path leading uphill to the left joins an old track which continued all the way along the edge of the field to a ford at the head of the creek. This is recorded on the first edition OS maps from the 1880s. A quarry (marked as "old" in the 1880s) was located in the field on the other side (on the way to Messack Farm). As well as for extracting stone, it's also likely the track was used to get livestock on and off Messack Point. Another quarry operated in the early 20th Century on this side of the valley with a short track connecting to this one part-way down the field.

  23. Cross the driveway to the path opposite and follow this back to St Just churchyard to complete the circular route. You can follow the path leading from the stile just before the Holy Well as a short-cut to get to the drive leading up to the car park.

    During late winter or early spring, if you encounter a patch of plants with white bell-shaped flowers, smelling strongly of onions, and with long, narrow leaves then they are likely to be three-cornered leeks. Once you're familiar with their narrow, ridged leaves, you'll be able to spot these emerging from late October onwards.

    Three-cornered leeks are native to the Mediterranean and are first recorded as being introduced to the UK in 1759. By Victorian times, they had become well-established in the wild. They thrive in the moist, mild climate in Cornwall and are salt-tolerant so will grow almost anywhere, even on the coast.

    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.

The name for the Roseland Peninsula derives from the Celtic word ros which can be used to mean a number of things including "moor", but the meaning most applicable in this case is "promontory".

The parish of St Just in Roseland was recorded in 1046, just before the Norman invasion, as "Ecciae Sci Juste".

The first records of the settlement around the church are a little later, from 1202, but this used the Cornish name Lansioch. The name contains the Cornish word lann, meaning "enclosed cemetery", which is typical of settlements dating from the Dark Ages. The remainder of the name is thought to be from a Celtic saint's name. It's therefore likely that the church is on the site of an older churchyard, possibly dating from the Dark Ages, and the presence of the Holy Well further supports this.

When maintenance work was carried out on the church in the early 20th Century, a Roman coin was found beneath the floorboards, indicating that there may have been settlement in the vicinity of the church prior to the Dark Ages.

Some estimates suggest the UK has up to half of the world's total bluebell population; nowhere else in the world do they grow in such abundance. However, the poor bluebell faces a number of threats including climate change and hybridisation from garden plants. In the past, there has also been large-scale unsustainable removal of bulbs for sale although it is now a criminal offence to remove the bulbs of wild bluebells with a fine up to £5,000 per bulb!

During periods of cold weather, spring flowers, such as bluebells, have already started the process of growth by preparing leaves and flowers in underground bulbs during summer and autumn. They are then able to grow in the cold of winter, or early spring, by using these resources stored in their bulb. Once they have flowered, the leaves die off and the cycle begins again.

Other species (such as cow parsley or dandelions) require warm weather before they are able to germinate and grow. With the warmer springs induced by climate change, bluebells lose their "early start" advantage, and can be out-competed.

Because bluebells spread very slowly, they're considered to be an indicator of ancient woodland sites. In areas where trees are not very old, the fact there are bluebells around can indicate that there has been a wood on a site for a very long time. Even if there are no trees there at all, bluebells tell us that there was woodland there some time in the past. The bluebells along the coast are a relic of the gnarled oak woodland that used to grow here before it was cleared for grazing. There is still a patch of the ancient oak woodland left along the coast at Dizzard.

Some plant nutrients such as phosphorus tend to be more abundant near the surface of the soil where decaying organic matter collects. Bluebell seedlings start life at the surface so these are OK but as bluebell plants mature and send their roots deeper into the soil to avoid winter frosts, they have a phosphorus problem. They have solved this by partnering with a fungus that extends from their root cells, drawing in minerals from the soil in return for some carbohydrates from the plant.

Bluebells are extremely poisonous, containing a number of biologically-active compounds and were used (probably with varying success) in mediaeval medicine. The sap was used as a glue for book-binding as its toxicity repelled insects. It was also used to attach the fletchings onto arrows.

In Elizabethan times, starch made from the bulbs was used to stiffen collars and cuffs in clothing. The ruffs that were highly fashionable at the time would have needed a lot of starch to prevent them flopping. The toxins in bluebell sap might also have had the desirable property of preventing the starch encouraging the formation of mould.

In folklore, the bluebell is a symbol of constancy, presumably based on the fact that they flower in the same place every year. It was said that anyone who wears a bluebell is compelled to tell the truth. This could be the origin of the "…something blue…" that a bride should wear on her wedding day.

According to folklore, it's unlucky to bring bluebells into a house and also unlucky to walk through bluebells as it was thought that the little bells would ring and summon fairies and goblins.

In Old Cornish, both bluebells and marigolds were known as lesengoc which translates to "flower of the cuckoo". In Modern Cornish, the marigold has remained more-or-less the same but the bluebell has been changed to bleujenn an gog ("plant of the cuckoo"). The association between bluebells and cuckoos exists in Welsh ("bells of the cuckoo") and Gaelic ("cuckoo's shoe"), and in some English folk names such as Cuckoo's Boots and Cuckoo Stockings. It is thought that the association is due to the time that bluebells flower coinciding with the time that the call of the cuckoo is first heard.

Bluebells are also known by folk names based on their shape including Lady’s Nightcap and Witches’ Thimbles.

Other common names for the bluebell include "wild hyacinth" and "wood hyacinth" as they are related to the hyacinth family. Their Genus name Hyacinthoides also means "hyacinth-like".

When photographing bluebells, the flowers that look blue to your eye can end up looking purple in photos.

The first thing to check is that your camera isn't on auto white balance as the large amount of blue will cause the camera to shift the white balance towards reds to try to compensate.

Another thing to watch out for is that the camera's light metering will often over-expose the blue slightly to get a reasonable amount of red and green light and the "lost blue" can change the balance of the colours. You can get around this by deliberately under-exposing the photo (and checking there is no clipping if your camera has a histogram display) and then brightening it afterwards with editing software.

Bluebells are very vulnerable to trampling. The reason for this is that when their leaves emerge in the early part of the year, they are powered by the stored sugars in their bulbs. Sunlight is very limited at this time of the year and even more so in the shady places where they grow. In order to survive, they then need to photosynthesise flat-out to store enough starch in the bulb for next year's growth. If a bluebell’s leaves are crushed, it cannot photosynthesise and and doesn't have enough reserves left in its bulb to grow new ones. It's therefore important to stick to footpaths in bluebell woodland and best to take photos with a zoom lens from there as wandering around in the bluebells to take photos will inadvertently kill them.

A rare genetic mutation occurs in bluebells which results in about 1 bluebell in 10,000 being white rather than blue.

Three-cornered leeks - which have white bell-shaped flowers and are very common - are often misidentified as "white bluebells". The easiest way to tell them apart is that 3-cornered leeks smell strongly of onion. Their flower stems are also triangular (hence the name).

Oystercatchers are recognisable by their black-and-white bodies, their long, straight red beaks and loud, piercing call. In flight, the white markings form an image of a white bird towards the back of their otherwise black backs which may have evolved to confuse predators.

The long beaks are adapted to open shellfish - mainly cockles and mussels - "cocklecatchers" would be a more accurate name. They can also use their bill to probe for worms.

Gunnera looks like giant rhubarb but the leaves stems are spiky. It tends to favour damp places as quite a lot of water is needed to supply its huge leaves.

The plant has a symbiotic relationship with cyanobacteria which live between its cells. The cyanobacteria, also known as "blue-green algae", are photosynthetic and also supply the host plant with nitrogen which allows it to colonise poor soils.

Grey mullet are related to the perch family (which includes bass) and are surprisingly unrelated to the "red mullet" (which is in fact a type of goatfish). Mullet caught in the open sea are excellent eating fish and can be used in similar dishes to bass. However, those living in muddy water (such as the harbour) generally taste of mud. This can apparently be diminished by soaking them in acidic, salty water but the flavour is still described as "earthy".

Native oysters rarely produce pearls (Pearl Oysters live in warmer seas) although all molluscs theoretically can and most would be tiny. The commercial value from native oysters comes from eating them and it takes around 4-5 years for an oyster to reach full size.

There is evidence as far back as 8700 BC of Stone Age hunter-gatherers harvesting oysters. At Tintagel castle, oyster shells were found in a refuse tip from the "Dark Ages" (Celtic Early Mediaeval period in Cornwall) which have been dated to around the 6th Century. Following the Norman Conquest of 1066, oyster beds were valuable enough to be recorded in the Domesday survey.

Native oysters were overfished in the 20th century, and in the 1960s, pacific rock oysters began to be imported into Britain. Native oysters can be distinguished from imported pacific oysters by the shape of their shell. Pacific oysters have pointed shells (a bit like knobbly mussel shells) whereas the shells of native oysters are round.

Oysters feed by filtering plankton from seawater and a single oyster can filter around 100 litres of water per day. As with mussels, during the warmer months (May-Aug, remembered as not containing the letter "r"), plankton species which are poisonous to humans are around which can accumulate in shellfish and cause tummy upsets. Consequently the Falmouth Oyster Festival is in October.

Tregorland was recorded in 1302 not as a farmstead beginning with "Tre" but as Kaercorlan. The name is derived from the Cornish words for "fort" and "enclosure" which suggests that an Iron Age hillfort was located somewhere in the vicinity. Within the fields, there are crop marks visible on aerial photographs which are thought might be the remains of Bronze Age Burial mounds.
