Standing on a rocky promontory jutting out into Loch Assynt in Sutherland, north west Highland, Scotland, Ardvreck Castle is a ruined castle dating from the 16th century.
The ruins can be reached by driving along the A837 which follows the north shore of Loch Assynt from the village of Inchnadamph. Care should be taken when walking around the site as falling masonry is a possible danger.
The castle is said to be haunted by two ghosts, one a tall man dressed in grey who is supposed to be related to the betrayal of Montrose and may even be Montrose himself. The second ghost is that of a young girl. The story tells that the MacLeods procured the help of Clootie (a Scottish name for the Devil, deriving from 'cloot', meaning one division of a cleft hoof) to build the castle and in return the daughter of one of the MacLeod chieftains was betrothed to him as payment. In despair of her situation, the girl threw herself from one of the towers and was killed.
