A field system with associated houses partially shown on the current OS map and on RCAHMW Aerial Photographic Interpretation. Located on the east side of the Afon Ddu. On the south side there is a rectangular fieldsystem. The house consists of a long irregular wall running roughly north-east to south-west and has at least two internal dividing walls, which are approximately 90m long by 30m wide. The collapsed walls are a maximum of 0.65m wide and up to 1m high. There is a two celled hafod structure, 4.5m wide, located on the northeast corner, which is shown on the current OS mapping at SH 72593 67742. The rectangular field system corners are SH 72616 67789, SH 72650 67779, SH 72585 67709, SH 72564 67731. The field system possibly went further west but is cut by a disused leat. There is an additional, substantial, longhouse on the west end, measuring approximately 10m long by 5m wide. The walls are 0.7m thick by up to 0.6m high. Only one cell is visible, and the longhouse is embanked up. Has a possible earlier phased enclosure beneath the west end of the field system, shown as a two celled square on the RCAHMW Aerial Photographic Interpretation, but difficult to make out the form on the ground.
