Carn Marth
Carn Marth is 235 metres high and like Carn Brea is formed from an outcrop of granite which pushed up through the original rocks to form a hill. From the top, the hills of Bodmin Moor can be seen and a topograph (being restored at the time of writing) near the lake indicates the locations of surrounding landmarks. Carn Marth has therefore been used as a site for a beacon for many centuries, including as part of the Tudor early warning system where a chain of hilltop fire beacons was used to warn of an invasion. The remains of 3 barrows suggest that it has been important since prehistoric times and an urn with a Roman coin suggests this continued into the Dark Ages.
