It is an irregular four-sided bawn with the entrance in the north wall. There are large rectangular flanking towers at the north-east and north-west corners and a smaller round tower at the south-east corner It is built on a limestone cliff overlooking the River Blackwater, the border between County Tyrone and County Armagh. A 19th-century tower house occupies the south west area of the bawn. The castle is in excellent condition having been recently restored and stands in the grounds of the imposing Servite Priory, a religious order based in the village.
