The footings of a rectangular building measure 9.5m (NW-SE) by 3.7m defined by low stony banks 1.5m wide and 0.3m high. Rounded corners at NW and ?SE ends. No obvious entrance. Around the NE, S and SW sides there are low outer banks parallel with those sides as if the building were placed near the S corner of a small enclosure.
Many hollow trails from Llanharan onto Mynydd Meiros pass nearby.
