terryglass old court castle

The castle was probably built by Theobald Walter Butler some time early in the 13th century, and the Butlers still owned it in 1640. the castle is square in plan with rounded turrets at the corner, but only one storey of the original three or four remain. The tower on the north-east is only enterable by steps up from the outside. The interior of the castle was divided into two apartments by dividing wall. Access to the castle is by foot only, as it's located on private land.

In the nearby village is an Early Christian church modified in the 15th century, standing on the site of a monastery which was famous for its ascetic monasticism during the so-called Culdee movement in the 8th and 9th centuries.
