According to Paul Davis, the remains of Rhiwgarn (or Cymmer) long-hut are now 'grass-covered footings of a substantial long-hut, 11.8 by 7m overall, located on the brow of an escarpment overlooking Rhiwgarn farm. There appear to be entrance gaps in both side walls, and a shallow hood around the south gable. A wall leads from the north end to connect with the adjacent field system. Close by are the ruins of a later hafod.'
