Llettau at Pentrehobyn

Low single-storey rubble stone range with massive stone slab roof divided into eight small cells and an attached 2-storey, part ashlar, block to the downhill (east) end believed to have been occupied by the warden or overseer. Each cell has a boarded door under a canted dressed stone lintel and a flanking tiny round-headed ventilation opening. Modern inscribed plaque to centre. The eastern two lletty have circular vents and slightly wider doorways. The 2-storey warden's house beyond is built of finer, partly ashlar, masonry and has gable parapets, simple rounded kneelers and a ball finial to the east gable apex; the other gable has stone chimney stack with weathercoursing. Plinth to east and north sides. The north side has outside stone steps to the upper floor. The main entrance was to the south side with canted Tudor-arched door below a 2-light window with rounded heads. The gable end has rectangular attic window and a camber-headed ground-floor window that has been lengthened through the plinth to form a tall but narrow doorway. Stepped up to the west is the rubble linking wall with pointed coping and small boarded door in chamfered opening with large jambs.

Individual cells are of slightly different sizes but all have cobbled floors and simple barrel vaulted stone roofs. They are about 1.8m high and 2m wide. Renovated interior to warden's house.
