Cadw's description

A country road branches E off Fonllef Hir and leads to the Cwm Bychan road; c4km NE of Llanfair it passes through the farmyard at Gerddi Bluog. The barn is to SSW of the house and lies at right angles to the E side of the road.

Early C18 barn, dated by an inscribed stone set in the E gable apex which bears the date 1728. Re-slated in C20 and extended in the C20 by a single pitched addition along the N lateral wall.

Early C18 barn built of rubble masonry; slate roof laid to diminishing courses with tiled ridge and stone copings. The entrance is through a central doorway in the E gable which has a small opening set in the apex above. The W gable has a pitching hole to the loft and there is a slate slab set in the gable apex which bears the inscription: MORGAN PRYS / HYDREF : Y : 31 : / 1728 W H / PEN SAUR.

The 2-bay roof has a pegged and chamfered collared truss.

Included as an excellent example of an early C18 barn which forms a group with the house and other ancillary buildings at Gerddi Bluog; a good example of a C18/C19 upland farmstead.
