Description
This is a long barn constructed of rubble, originally limewashed, and roofed with stone slates. It is divided into two units, with the left-hand unit likely being the older of the two. At the left gable end, the higher ground allows for a loft entrance with a six-pane window beside it. On the front elevation, similar windows are positioned on either side of a doorway, with a dormer window on the rear elevation. The lower end of the barn, to the right, features a unit with double doors and an added lean-to.
