The Power and Pride of Ferns
Ferns Castle was built in the 13th century by William Marshal, one of the most powerful Anglo-Norman lords of the time. Though originally much larger, only about half of the original structure remains today—but what’s left is still striking. One of the massive circular towers is almost fully intact, and if you’re up for it, you can climb to the top for sweeping views of the surrounding countryside.
This wasn’t just a military outpost—it was also a statement of dominance. Ferns itself had long been a place of importance, once the capital of the Kingdom of Leinster and the burial place of Diarmait Mac Murchada, the controversial king who invited the Normans into Ireland in the first place. So it’s no accident the Normans built their castle here—they were quite literally planting their flag in the heart of Irish resistance.
A Castle of Surprises
Inside the surviving tower, you’ll find a rare and unexpected feature—a beautifully preserved chapel. This small space, with its elegant ribbed vault and carved stone details, is a reminder that Ferns was both a military and spiritual stronghold. There’s also a well-preserved vaulted basement, once used for storage or possibly even as a prison.
Local lore says there may be a tunnel connecting the castle to the nearby cathedral ruins, though no one’s quite managed to prove it. Still, it’s fun to imagine monks and messengers slipping unseen through secret passageways beneath the ground.
Visiting Ferns Castle
Admission is free, and during the summer season, you can join a guided tour led by knowledgeable and friendly OPW guides who’ll fill you in on all the best tales. It’s a relatively small site, so you can take it in at a relaxed pace—perfect for pairing with a visit to the nearby cathedral ruins or a bite to eat in the village.
Practical Tips
Ferns is located in County Wexford and is easiest to reach by car. There’s parking nearby and signage throughout the village to help you find the castle. Wear sturdy shoes if you plan to climb the tower—it’s a bit of a spiral stair workout but worth every step.Insight
