An open sided rectangular structure beside a track with one corner abutting a field wall. Drystone built with three walls around a level interior. A short length of additional wall, possibly added at a later date closes the open front at the SE. This barn is probably associated with a cottage nearby that is now a ruin within the later processing works of the Cwm Bychan copper mine. Dimensions: 6m x 5m overall, walls 2m high and 0.8m thick.
