Dunrobin Castle, on the east coast of Scotland, has been the ancestral seat of the Duke of Sutherland's family for centuries. It is considered the largest inhabited estate in the northern Highlands.
History+
The origins of Dunrobin Castle date back to the 13th century, when a keep formed the core of the later complex, the remains of which are still visible in the courtyard today. The fortress was first mentioned in a document in 1401 under Robert de Moravia, the sixth Earl of Sutherland. In the 17th century, the old castle was extended with two new wings, connected to the existing structure by a tower with a spiral staircase. Between 1845 and 1851, under George Sutherland-Leveson-Gower, the 2nd Duke of Sutherland, the castle acquired its present appearance, strongly inspired by French château architecture.
