Remains of the medieval Dominican priory on the west side of Carlingford, recognisable by its high, narrow windows and the elongated ruin wing in grey stone. The site lies quietly just outside the centre, with views of the hills and the open grass around the old priory walls.

This charming seaside town overlooks the Mourne Mountains, whose silhouette rises along the coast of Northern Ireland. Carlingford is very lively at weekends thanks to its many pubs and restaurants, which attract visitors from the north, and is famous for its oysters. The village has several historical sights, such as the small King John's Castle, with its romantic silhouette overlooking the sea, and Taaffe's Castle, a former 16th-century merchant's house located a little further from the quay.

The Tholsel is undoubtedly one of the most unique structures in the heart of Carlingford. This medieval city gate, originally built in the 15th century, is the only remaining gate from the original town wall and served for centuries as the ceremonial and administrative entrance to the town.

The former Carlingford Railway Station is a beautifully preserved reminder of the time when the steam train was the lifeblood of the Cooley Peninsula. The station was once an important stop on the Dundalk, Newry & Greenore Railway (DN&GR) line, opened in 1873 and closed in 1951.

Above the medieval street pattern, which dominates the silhouette of Carlingford, stands the imposing ruin of Carlingford Castle, also known as King John’s Castle. This castle was built around 1190 by the Norman knight Hugh de Lacy and was for centuries the strategic key to the entrance of Carlingford Lough.
