Description

The barn and stable at Gwenlais-uchaf date from the 19th century and are constructed from whitewashed rubble stone with a single slate roof. The barn, located on the right, features two large openings with plank doors and timber lintels. The stable on the left has a door and a boarded 2-light window, both also with timber lintels. The left end wall of the building has been altered, with the apex rebuilt in cement block. The right end includes two small openings. At the rear of the barn, there is one central opening with a timber lintel, which is lower than the front openings, along with two vent loops to the left.
