Ballyreagh Castle ("the Royal Castle", Dunfert Castle) Ruins Castle? - The scant remains of this castle consists of one small mortar & basalt boulder wall - part of the E-W wall which once cut off the landward approach, i.e. the S wall of the castle. The mortar has flint & pebble inclusions. The W edge of the promontory shows a slight lip 0.6m high, which could reflect a buried wall, but this is doubtful. The wall remnant is at most 0.9m high & from the wall to the edge of the promontory is 20m.
