February 23, 2026, Taaffes Castle

Taaffe's Castle is a fortified merchant's house dating from the early 16th century, built by the wealthy Taaffe family, who later became the Earls of Carlingford. Situated near the old harbour, the building originally served as a trading post on the ground floor with residential floors above. The architecture displays typical defensive features such as machicolations, narrow loopholes, spiral staircases, and multi-level garderobes. [curiousireland.ie], [castles.nl], [carlingfor...centre.com] The main structure is a four-storey rectangular tower, later extended with a 16th-century northern extension. Its location and construction clearly demonstrate Carlingford's importance as a thriving trading town during that period. After the 17th century, it fell into disuse, and eventually fell into disuse. Today, it forms part of a pub complex and remains a striking example of medieval urban defensive architecture in Carlingford.

The approach takes you through picturesque streets lined with green fields and old stone walls before you reach the ancient castle. The castle itself is fairly well preserved, although the ravages of time have left their mark here and there. It's worth stopping for a moment and taking in the atmosphere, as the place tells its own story - even without many words. This three-story tower house, dating to the 15th or 16th century, exudes a quiet grandeur that fits perfectly with the idyllic surroundings. If you want to explore it a little more, you can pick up the key from the neighbor - an unusual but charming way to gain access.
