Once built as a medieval fortress on the site of the 'Black Pool' (Dubh Linn), today you will mainly recognize the imposing 18th-century architecture and the characteristic medieval Record Tower. As you walk or cycle across the courtyard, you will pass the richly decorated State Apartments and the neo-Gothic Chapel Royal.

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.

This Cistercian abbey, located in a valley northeast of the peninsula, was founded in 1200 by the Norman William de Clare. During his first trip to Ireland, he was caught in a storm and vowed to found an abbey if he survived. Monks inhabited the site until the 16th century, after which the abbey was owned by the Colclough family for almost 400 years. The complex, which offers a very photogenic view from the fortified bridge, has preserved beautiful remains, including an imposing crenellated tower.
