Founded during the 13th century, Drimnagh Castle remained continuously occupied until 1953. It is a picturesque and modest-sized building, and its large flooded moat has recently been repaired as part of the castle's programme of The moat probably dates from the late 13th century, but the castle is quite a hotch-potch of different periods. The gateway tower belongs largely to the 16th century, the stone mullioned windows are 17th century, while the entrance porch and stone staircase were added a century later. The great hall was restored in 1988 with a minstrel's gallery, arched sandstone fireplace and trussed oak roof. The formal garden was created in 1990 featuring plants known in Ireland during the 17th century.1 km (0.6 miles) W of Crumlin Children's Hospital, Long Mile Road.
