Murrisk Friary, a small Augustinian house on the south shore of Clew Bay in the shadow of Croagh Patrick, was founded in 1457 by Hugh O'Malley and dedicated to St Patrick, some of whose relics were preserved there. The surviving remains are the small church and the domestic range on the east side of the cloister, with the chapter house below where the friars met to discuss business and read the daily chapter of the order's rule, and the dormitory above; the cloister itself has disappeared. The church has unusual battlemented walls and a fine east window that once cast sunlight onto the altar, and its bell tower stood at the west end rather than in the more usual central position, though it had fallen before the end of the 18th century.
