Treen Common Circle Enclosure
Located on the West Penwith moors, as they drop back down towards the north coast is this apparent stone circle. It seems much of the time the stones are obscured by the gorse and heather, however, after a recent fire they were quite visible from the road.
The actual nature of this site is something of a mystery. Although I've referred to it as Porthmeor Stone Circle it is possible it is actually the remains of an Iron Age enclosure.
The arrangement of stones here is quite different to nearby stone circles; the diameter is significantly larger at over 30 metres (100ft) and the 14 upright stones seem to lack uniformity. Of note is the tall stone at the south of the circle, which is more in line with what we would expect from a typical stone circle.
