Cusop is a village in W Herefordshire, immediately SE of Hay-on-Wye on the Welsh border, formed by the Dulas Brook at this point. The village is on the E side of the brook, under Cusop Hill, and consists mainly of farm buildings and cottages, although there are the sites of two castles within the parish. The church consists of a broad 13thc chancel, and a 12thc nave with a S porch, a N vestry and a timber bell-turret added over its E end in 1961. The church was restored by J. P. St Aubyn in 1856-57, and he rebuilt the W front, added the porch and the vestry and replaced the E window. Romanesque work is found on the 2 nave doorways, the chancel arch and the font.
