Description

The barn at Glyn Bran Farm is an outbuilding constructed from rubble stone and topped with a metal sheet roof. It is built on a slope, featuring a tall left gable end. The structure appears to have been rebuilt in the 19th century, with squared stone and two loops located in the apex. The front side facing the road has two doors on the left with altered heads, a taller central door with a renewed lintel, and an additional door at the extreme right upper end, which has a head positioned under the eaves. There is significant evidence of alterations in the stonework, and a lean-to has been added to the rear.
