The monument consists of a cave containing archaeological deposits situated on a steep, wooded slope. The outer chamber measures approximately 1.5m to 2m wide and 1.3m high with a small platform outside the entrance. The cave extends 6m into the hillside and beyond this is a smaller passage, measuring approximately 0.5m by 0.8m that extends at least another 25m into the hillside.
