Description

This is a barn range at Wernddyfwg, constructed from rubble stone and topped with an asbestos sheet roof. The large barn features two sets of high double doors, each set flanked by a vent loop on either side, with an additional vent loop located at the extreme right. Each vent loop consists of two short loops stacked one over the other. Attached to the left of the barn is a lofted stable, which has a gable that breaks over a square boarded loft door. This loft door is situated above a stable door, with a window on each side, all of which are framed with timber lintels.
