The site of a deserted long hut, on the northwest-facing slopes on the eastern side of Cwm Cwareli, which is now only represented by wall bases overgrown with grass and bilberry, with reed growth over the interior of the structure. The long hut measures c.13m northwest-southeast by a maximum of 5m wide. Along the outside of the lateral wall forming the southwestern side of the structure runs a gully, possibly a drainage feature. A similar, though less well defined gully is seen along the outside of the opposite lateral wall. The wall bases are about 1m wide at base, and less than 0.5m high. An enclosure (NPRN 246149) is associated with the long hut, and they are both part of deserted rural settlement NPRN 275642, and are Scheduled Ancient Monuments. J.J. Hall, Trysor, 28 June 2008.
