Bonamargy Friary is situated in County Antrim, Northern Ireland, off the Cushendall Road on the approach to Ballycastle. The name Bonamargy means ‘foot of the Margy River’, the river formed by the joining of the Cary River and Shesk Rivers.

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.

Perhaps the Friary’s most famous resident was the 17th century prophet and recluse Julie MacQuillen. Known as ‘The Black Nun’, MacQuillen wished to be buried at the entrance of the chapel so that she might be trodden under the feet of those who entered. A round holed cross marks her grave
