Skibo Castle was originally a 13th century stone keep and courtyard fortress, founded by Gilbert de Moravia, Bishop of Caithness. Rebuilt into a large fortified palace, it remained the residence of subsequent bishops until 1545, when the estate was given to John Gray. In the 19th century, the castle was absorbed in the construction of a majestic baronial mansion house, founded by Andrew Carnegie.
