A wall, terraced into the hillside, which is approx. 3.2m tall at its highest point. The structure is constructed from well-built coursed rubble blocks which range in size from 20cmsq to 1msq. This feature seems to represent an incomplete dam project which would have been a much larger structure than the existing dam below.
