Two small standing stones standing apart in sloping pasture, divided by an old trackway or bank. The name translates as ‘the stones of the lamb’ (source: Os495card; SN68SE11). That to the east is the larger, a rectangular flat slab, while that to the west is a far smaller pointed stone. Both stones appear to occupy small platforms shelved into the hillslope, but the apparent platform below the western stone seems to be a lump of naturally outcropping rock, rather than an artificial platform. The stones are overlooked from the north-east by a large rounded outcrop in the field, which has the form of a Bronze Age barrow but is again a natural feature. It is entirely possible that its resemblance to a burial mound influenced the siting of the two standing stones here. A further possibility advanced by Simon Timberlake is that the two stones mark the line of a longer Bronze Age trackway coming up from the coast, via Clarach, Gogerddan and Penrhyncoch, and climbing into the foothills around Plynlimon passing other standing stones (see: Timberlake, S., 2001. Mining and prospection for metals in Early Bronze Age Britain: making claims within the archaeological landscape. In: Bruck, ed., Bronze Age Landscapes: Tradition and Transformation. Oxbow, 179-192.). This is a possibility, although difficult to prove, as these stones command spectacular views west along the valley of the Nant Silo.
