This structure is 30m north-west of Penally Court Farmhouse (and within its grounds), adjacent to the main street of the village and opposite St Nicholas's Church [NPRN: 400386]. There is the surviving gable and south lateral wall of a building of possible medieval date in rubble masonry, roughly brought to courses, the walls being approximately 0.6m thick. The surviving south wall merges into the farmyard wall, and it is unclear how extensive it was originally, or which of the openings in it might be original. The height of the surviving gable implies a building of considerable size. The gable faces west to the road and has a large blocked opening with a two-centred head. Between the gable and the boundary wall is a lean-to with a door at the north. At the rear of the gable is a lean-to structure with a low sheeted roof, overlying the lost north wall. It was listed as a possible mediaeval barn or large house. At one time it was known as the ruins of the Court House.
