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.

Perfectly placed on the beautiful Shores of Carlingford Lough, this was a 13th century Norman keep, a replacement tower house and bawn was built at Narrow Water in the 16th century. The replacement structure, built in the 1560's, was a typical example of the tower houses built throughout Ireland at the time. The castle was damaged during the Irish Rebellion of 1641, and sold to the Hall family in the 1670's. It was occupied by the Hall family until they built an "Elizabethan revival style" mansion in the early 19th century. This Mansion is also called Narrow Water Castle.
