Discover more about Ballymoon Castle

Ballymoon Castle, located a few kilometers east of Bagenalstown, County Carlow, is a captivating historical site despite its unfinished state. Thought to have been constructed in the 13th or early 14th century, the castle's origins are somewhat unclear, with some attributing it to Roger Bigod, the 5th Earl of Norfolk, or the Carew family. The castle was intended as a defensive fortress, but its construction was never completed.The castle's structure is characterized by a square courtyard, with each side measuring approximately 24 meters (80 feet), enclosed by granite walls that stand roughly 6 meters (20 feet) high and 2.4 meters (8 feet) thick. Square towers project from three of the sides, while the fourth features a formidable gatehouse. The interior of the castle is now bare, though evidence suggests there were once two-story structures built against the inner walls. The large double fireplace on the north side indicates the location of the great hall.What makes Ballymoon Castle particularly intriguing is the air of mystery surrounding its history and purpose. Local legend suggests the castle was never finished or inhabited. The presence of numerous garderobes (latrines) and fireplaces suggests that the castle was designed with both defense and comfort in mind. Today, visitors can explore the ruins, walk along the walls, and imagine what the castle might have looked like in its prime.
