Fron-gelyn Barn

A 4-bay threshing barn in local axe-dressed masonry with slate roof, sited downslope. As seen from the farmyard to the south, the left 2 bays are lofted; there is a stable or calfhouse with door and window beneath in the left bay. Small window in the second bay, where there is said to have been a chaff cutter, and slit ventilators above and below. The full-height barn door is in the third bay, and there is an ordinary 3-quarter-height door in the fourth bay.

At the left gable is a low lean-to in similar materials, with door to the front, and 2 tiers of slit ventilators in the gable above.

The threshing engine formerly stood at the rear (to north) and there is a slit in the wall for a power drive to the machinery in the barn. At this side there is now a modern livestock shed.

Threshing floor in the third bay between opposed doors, flagged. The 2 bays to left have their loft floor. Trusses with V struts, 2 purlins each side. The trusses each side of the threshing floor have central posts from ground to tie beam.

There was formerly a chaff-cutting machine in the ground part of the second bay.
