Dounreay Castle, Scotland
Dounreay Castle dates from the late 16th century, and is one of the few remaining examples of a Scottish Laird’s castle from that period. William Sinclair of Dunbeath, descended from a younger brother of John Sinclair, third Earl of Caithness, built the castle in the 1560s. It was damaged in 1651 by Oliver Cromwell’s New Model Army during their Scottish campaign. Now entirely ruined, the castle was still inhabited in 1863, but had become roofless and derelict by 1889. The castle is on the north coast of Caithness, in the Highland area of Scotland.
