Usually called a hospital, but sometimes a chapel or chantry. The roofless remains consist of a chapel 6m wide and 9.7m long with a later building, 6m wide and 5m long, at the west end. The east wall, about 7m high, contains a window of 3 lights to full height with a circular window above. In the south wall is a large segmental arched doorway, a smaller ogee-headed doorway and two decorated windows. The north, west and south walls are about 4m high.
