A sub-rectangular enclosure, c.8.0m by 4.0m internally, defined by a bank, 3.0-3.5m across, a 3.0m wide rock-cut ditch and a further bank, 7.0-9.0m wide. There is a causewayed entrance to the NW. The name 'Fforest Castle' may indicate the monument's original function. (Coflein)

The monument comprises the remains of a motte and ditch, dating to the medieval period (c. 1066 -1540 AD). The motte is roughly oval, measuring 30m by 26m and 3m-5m high, surrounded by a rock cut ditch 3m wide. The top of the motte has a deep depression in it. An outer bank, 9m wide and 1.3m wide encircles the ditch and there is a causewayed entrance on the NW side. (Scheduling Report)

Gatehouse Comments

Pettifer identifies this as a ditched enclosure of a later medieval stronghold, Remfry as possible early Welsh castle. Was this built as a hunting lodge and administrative centre at a relatively late date or was an earlier castle adapted for this. The location on the hill may suggest a later date since the strategic military location would be nearer the point where the Roman road crosses the Afon Cammarch although this may be a matter of debate.
