Built by de Courcy for the Cistercians in 1180 on an earlier Irish monastic site, Inch Abbey is visible across the river from Down Cathedral. The English Cistercians had a strict policy of non-admittance for Irishmen and maintained this until the end in 1541. Most of the ruins are just foundations and low walls; the neatly groomed setting beside the marshes of the River Quoile is its most attractive feature.
