Dunluce Castle, a dramatic medieval ruin perched on the basalt cliffs of the North Antrim coast in Northern Ireland, is one of the most atmospheric locations associated with banshee traditions. The castle was the seat of the MacDonnell clan, chiefs of Antrim, from the 16th century onward, and the MacDonnells are among the families traditionally attended by a banshee. The castle's position — jutting out over the Atlantic on a promontory connected to the mainland by a narrow bridge — makes it an ideal setting for supernatural encounters.
According to tradition, the banshee's wail could be heard keening on stormy nights, carried on the sea wind that batters the cliffs. The most famous incident associated with the castle occurred in 1639, when the kitchen building collapsed into the sea during a storm, taking several servants to their deaths. Local tradition holds that the banshee was heard wailing in the days before the disaster.
The castle was abandoned shortly afterward, and its haunted ruins have attracted visitors fascinated by the supernatural ever since.
