Clonmore Castle is a typical 13th-century Anglo-Norman castle - plain and square with two rectangular towers and two turrets at its corners. These fortifications were not enough though, to stop it being captured by the Earl of Kildare in 1516, the Earl of Ormond in 1598, and Cromwell in 1650. Near the castle a high cross can be seen and the remains of another nearby. Inside the castle, some of the original layout can still be seen.
