It is a late Franciscan foundation established in 1485 by Rory MacQuillan. It is said that the first battle between the warring MacDonnell and MacQuillan clans was fought on nearby land. At the main entrance to the friary is a small, two storey gatehouse which opens into a store and workroom. Well worn steps lead directly to the dormitory above. Traces of an altar can still be found in the adjoining church, and the locked vaults hold the remains of the celebrated chieftain, Sorley Boy MacDonnell, and several of the earls of Antrim.
