Narrow Water Castle
Narrow Water Castle is a sixteenth-century tower house at Warrenpoint in County Down, Northern Ireland, standing at the narrows where the Newry River enters Carlingford Lough with views across to the mountains of County Louth. The castle controlled this important waterway, which provided the main sea route for trade to the town of Newry and the agricultural hinterland of south Down and south Armagh. The tower house is one of the better-preserved examples of its type in south Down, its compact form reflected in the still waters of the lough at high tide. The castle is in the care of the Historic Environment Division and is accessible from the A2 shore road between Newry and Warrenpoint. The surrounding landscape at the head of Carlingford Lough, with the Mountains of Mourne rising behind Rostrevor, provides one of the most dramatic scenic settings of any castle in Northern Ireland.
