A shallow hollow fronted by a low mound possibly resulted from military activity. It lies a short distance from the Trecastle-Tafarn y Garreg road, above its west side. The hollow measures 3m (N-S) by 2.5m and 0.2m deep. It is flanked on the west by a low grassy mound measuring 5m by 3m and 0.2m high. The site overlooks the lower ground of the upper Tawe.
