Bonamargy (Bun na Mairge – Mouth of the river Margy). Friary, just outside Ballycastle, County Antrim, was built close to the mouth of the Carey and Shesk rivers by Rory MacQuillan in 1500. I am therefore unsure as to why the river Margy is quoted in the name. The rival MacDonnell clan fought for and claimed the friary from the MacQuillans in 1588. The cloister, gatehouse, altar and church are well preserved except for the thatch roof. There are many interesting features including the east window, a staircase and a sealed burial vault. The coffins of several Earls of Ulster and chieftain, Sorley Boy MacDonnell, lie within.
