As it stood in 1300

What Ballymoon Castle looked like in its prime.

A squat, square fortress defined by granite curtain walls roughly 80 feet (24 m) on each side, standing about 20 feet high with bases some 8 feet thick. The interior is an open courtyard ringed by the foundations and low remnants of domestic ranges; traces of two-storey structures cling to the inside faces. The western wall contains an arched gateway with visible portcullis grooves and possible barbican traces. Cross-shaped gun loops and narrow arrow slits puncture the stonework.

Its story

The story of Ballymoon Castle.

Much of Ballymoon's history is lost. The castle is thought to date from the 13th century, built either by Roger Bigod, 5th Earl of Norfolk, in turbulent times, or by the Carew family, who acquired the land when Bigod died without issue. The scant traces of interior structures beyond the foundations have led to speculation that it was never completed.

What stands is a square courtyard about 80 feet on each side, its granite walls 20 feet high and some eight feet thick at the base, with an arched western gateway grooved for a portcullis, and possibly once fronted by a barbican, plus cross-shaped gun loops and arrow slits in the walls. Foundations mark the doors and fireplaces, the large double fireplace on the north side belonging to the great hall. In the late 1800s the castle was bought by Michael Sheill of Wexford, and it is now a National Monument.
