This fine castle sits right in the middle of the village of Schrule and commands the bridge over the Black River on the Mayo Border. It was owned by the Chief of the MacWilliam Burke lochtair family who relieved it from an attack by the Lord President of Connacht, and the Earl of Clanricarde in 1570. The walls are nearly 9 feet thick at the damaged base giving it an impressively strong foundation and a strong resistance to incoming attack!
