Tre Heslog

View from the south east.

A single stone row measuring 5.2m long, including two medium and one large orthostats situated near a rock outcrop on a gentle south east facing slope. The row is orientated north east to south west and the stone used in its construction almost certainly came from the nearby outcrop. There are extensive views only to the east.
