A Castle with Two Faces
The King’s Castle
Carlingford Castle, also known as King John’s Castle, dates back to the late 12th century, built by the Norman knight Hugh de Lacy around 1190. Its strategic position on a rocky outcrop overlooking Carlingford Lough made it a key military post for controlling the narrow sea passage between the Mourne and Cooley Mountains.
In 1210, King John of England stayed here—hence the castle’s more popular name. His visit was part of a campaign to assert dominance over rebellious barons and Irish chieftains. The eastern section of the castle, including a large rectangular keep, is believed to have been completed in time for his arrival.
Expansion and Conflict
The western half of the castle was added later, likely in the 15th century, during a time of shifting power and frequent raids. You can still see the difference in masonry styles between the original Norman build and later additions.
Over the centuries, Carlingford Castle was embroiled in many conflicts—from Tudor power struggles to Cromwellian campaigns. It fell into ruin in the 17th century, but even in decay, it stands as a dramatic silhouette against the backdrop of Carlingford Lough.
What to See and Do
The castle isn’t just about its walls and towers—though they’re impressive in their own right. Wander through and imagine the clatter of armour, the smell of sea air mixed with hearth smoke, the watchmen scanning the horizon for sails.
From the top, take in sweeping views of the lough and surrounding mountains. It's easy to see why this spot was so coveted. Guided tours are available, offering deeper insight into the castle’s storied past.
The town of Carlingford itself is a joy to explore—full of narrow lanes, medieval buildings, and excellent places to grab a pint or a bite after your visit. Make sure to check out the nearby Tholsel Gate and Dominican Friary ruins while you're in town.
Planning Your Visit
Carlingford Castle is open seasonally, so check ahead before making your journey. It’s a short walk from the town centre, but do wear sturdy shoes—the path up is uneven and can be slippery after rain. The guided tours are well worth it, especially if you're a history buff or visiting with kids.
If you're in Carlingford during the weekend, pop into the local market for artisan treats and handmade crafts—it’s a perfect way to round off your castle adventure with a taste of local life.
