This Cistercian abbey, located in a valley northeast of the peninsula, was founded in 1200 by the Norman William de Clare. During his first trip to Ireland, he was caught in a storm and vowed to found an abbey if he survived. Monks inhabited the site until the 16th century, after which the abbey was owned by the Colclough family for almost 400 years. The complex, which offers a very photogenic view from the fortified bridge, has preserved beautiful remains, including an imposing crenellated tower.
