Description
National Monument in state ownership No. 491. Situated on an E-facing slope overlooking the River Liffey. Rectangular three-storey tower house with a projecting stair turret at the NE angle. It originally had a structure attached at the W side, where the springing of a barrel vault is visible. A doorway above the present entrance gave access from the original building to the later addition. Another barrel vault roofs the third floor in the surviving portion. Ascent to the first floor appears to have been by stairs in the W structure. This floor level has a large fireplace, decorative mouldings on the windows, and a garderobe with a chute built into the wall thickness of the stair turret. The site of another castle (WI005-032----) is indicated on the OS 6-inch map 300m to the E.
