Замок короля Джона

King John's Castle in Carlingford is the ruins of a medieval Normandy stronghold. They stand on the seashore and are currently primarily an interesting element of the local landscape. The castle consists of partially preserved defensive walls and a residential building.

The castle was built shortly after the Normandy invasion of the British Isles, at the end of the 12th century. Initially, it consisted of a tower and an adjoining wall. In the 13th century, the fortress was expanded. Throughout its history, the castle passed into the hands of various families. It was destroyed at the end of the 17th century during the wars with the troops of William of Orange.

Currently, the ruins are open to visitors. Only fragments of about 3 and a half meters thick walls have survived. They are two or three Tiers high.
