Deerpark Castle was a 15th century MacHubert-Burke tower house. The castle is a tall slim tower with a small guard chamber to the right of the doorway and a fragmentary spiral stairway to the left.
It was believed that the tower was intended to be part of a larger structure but there is no indication that other structures of the castle existed.
Unusually the tower seems to feature remains of a dovecote which seems to have been incorporated in the structure at some stage.
