Cong Abbey
Also known as the Royal Abbey of Cong, is a historic site located at Cong Co. Mayo. The ruins of the former Augustinian abbey mostly date to the 13th century and have been described as featuring some of finest examples of medieval ecclesiastical architecture in Ireland.
The grounds of the abbey also contain a monks' fishing house, probably built in the 15th/16th century on an island in the River Cong leading towards nearby Lough Corrib. The house is built on a platform of stones over a small arch which allows the river to flow underneath the floor. There is a trapdoor in the floor in which the fish may have been kept fresh.
