Chirk Castle (Welsh: Castell y Waun) is a Grade I listed castle that was built in 1295 by Roger Mortimer de Chirk, uncle of Roger Mortimer, 1st Earl of March. It was constructed as part of King Edward I's chain of fortresses across the north of Wales. It guards the entrance to the Ceiriog Valley. It is now in the care of the National Trust.

The castle is reputedly haunted by an apparitions of a lady in green which was witnessed by a child, the figure of a man in brown-coloured clothing, two soldiers carrying a third on a stretcher (although it is not specified from what era); the sounds of children running up and down corridors; and the touch of invisible tiny hands; and the occasional movement of objects.
