Well preserved round tower with a round-headed doorway on E. There are four windows with triangular gables at the top of tower facing N, S, E and W, and a smaller window with a triangular gable below the E window.

The early monastery was founded by Bishop Lughach, one of the earliest propagators of Christianity in Kerry. In the 13thc. the site was occupied by the Knights of St John of Jerusalem and subsequently by an abbey of Arroasian canons who remained there until the Dissolution. There are two churches adjacent to the tower which apparently belong to the later medieval period.

The carving over the doorway is without parallel in a round tower context, although the use of a raised broad band around a door opening with cross/apex decoration can be seen at Britway (Cork) and Killeenemer (Cork) and on the east window at Killodiernan (Tipperary).
