What survives of Ballug Castle, on the Cooley Peninsula, County Louth. This is thought to be a 15th or early 16th century tower house to which a gable-ended dwelling was added, probably in the late 17th century. Originally the tower would have had a barrel-vaulted ceiling but this has since collapsed, along with a spiral staircase occupying a turret in the south-east corner.
