Dunbeath Estate, with its spectacular castle perched on a high cliff-top promontory, lies on the north east coast of Scotland in the most northerly mainland county of Caithness, being 20 miles south of Wick and 90 miles north of Inverness.

In 1452 the lands of Dunbeath along with the Earldom of Caithness and other lands in the county, were granted to the Crichton family by King James II. Shortly after this these lands passed into the hands of the Clan Sinclair, becoming one of its principal strongholds, until being sold in 1945 by the late Admiral Sir Edwyn Alexander-Sinclair. Some of the buildings still bear the Sinclair crest.
