A well preserved single celled longhouse, located on the slope of Craig Henllan. It measures approximately 8m long by 5m wide with thick well-constructed walls up to 1m wide and 0.5m high. It is sat perpendicular to the slope, it is not cut into the slope but utilises a natural level shelf between outcrops as a base. P.J.Schofield, OANorth, 31st July 2008.
