About 3km (2 miles) from Moyne Abbey, Rosserk Abbey, sitting at the edge of the River Rosserk, is in many ways its twin. Both are evocative ruins, built at the same time, and destroyed at the same time by Bingham’s troops. Rosserk Abbey, however, is today in much better shape than Moyne. Its chapel windows are well preserved, and the piscina of the church (once used for washing altar vessels) is still here, carved with angels. On its lower-left-hand column is a delightful detail: a tiny, elegant carving of a round tower that recalls its 23m-tall (75-foot) counterpart in nearby Killala. Climb the winding stone stair for a lovely vista out across the bay.
