Description

The hay barn at the southwest end of the yard at Glandwr is a three-bay structure made of stone rubble with a slate roof. The exterior has been significantly altered, obscuring the original layout of the three open bays, which have been infilled with windows and a doorway on the front elevation, and with stone walling at the rear. However, the original character is still visible inside, featuring three open bays constructed with post and lintel. The roof includes two collar trusses.
