Near the chapel is Craignish Castle, originally home of the Campbells of Craignish. A castle was established here in the early 12th century, although the extant tower house dates from the late 14th century at the earliest. The castle withstood a siege by Alasdair "Colkitto" MacDonald in the 1640s. A new wing was added between 1698 and 1710, and offices and stables were added around 1770. In 1800 the estate was sold to Campbell of Jura, and in 1837 a new mansion was built on the side of the tower house, replacing the earlier extensions. Design of the new mansion has been attributed to either William Burn or Joseph Gordon Davis. In 1850 the estate was sold again to the Gascoignes of Parlington Hall, Yorkshire, who made yet more changes. Half of the 1837 mansion has since been demolished, and a stair tower added on the new gable.
