A barn associated with Pen-y-Bryn farmhouse (NPRN 27660). Derelict in 1989-90, the building had a corrugated iron roof and apparently featured a post and panel partition.
This is a rubble stone walled building and was originally a threshing barn with opposed cart entries. The southern section, which has three ventilation slits in its north wall, appears to be an addition. Two small wings were added either side of the north-western end.
