Trecastle Mountain - Y Pigwyn

Trecastle Mountain - Y Pigwyn

Trecastle Mountain (Y Pigwyn) has two circles made up of small stones. In the centre of the larger circle, which still has over twenty stones standing, is a small mound. To the southwest of the larger circle the smaller one is made up of five surviving larger stones. The site is close to the remains of two Roman forts and is located off the A40 between Brecon and Llandovery and via a lane just past Trecastle towards Cwmwysg and close to the Roman Road.

Our Visit

As you drive west through Trecastle look out for an Antiques Centre on the left side. Take the road beside that and just past some houses there is the old Roman Road to the right. It was late afternoon in Autumn when we visited. Eventually you come to a cattle grid and the road is not suitable for driving after that. Worth walking along that old Roman road and looking down at the spectacular views north towards the Usk Reservoir.
