Trecastle Mountain (Y Pigwyn) Stone Circles
Trecastle Mountain (Y Pigwyn) Stone Circles
One of the many prehistoric remains surrounding Brecks. There are two circles of small stones here, the larger measuring 74 feet in diameter. A small mound in the centre of the larger ring may indicate a burial.
The large circle is made up of over 20 visible stones, though there may have been more originally. All the stones are small, no more than 0.6 metres high.

The smaller circle, about 95 metres away, has only 5 stones remaining, standing up to 1 metre high. The entire circle is only about 8 metres across. Bronze age urns were discovered during excavations at burial mounds here.

The circles are very close to a pair of small Roman forts, or marching camps, and the course of a Roman road runs beside the site. A stone row and stone pillar are close by.

Getting There
From Trecastle take the minor road beside the antique centre and carry on until the public road ends at a cattle grid. The road at this point follows the route of an old Roman road. The trail rises steadily and curves to the right, towards the summit of Y Pigwyn. Leave the track and head towards the field boundary on the edge of the moorland. You'll come to the largest circle atop a low rise. Don't stay on the track/Roman road as neither circle is visible from it. A good OS map will be handy!
