Keith Inch Castle

Keith Inch Castle, or Tower, was a 16th century L-plan tower house and courtyard, about 1.0 mi east of Peterhead, Aberdeenshire, Scotland, on Keith Inch, to the north of Peterhead Bay.

An alternative name was Keith Insch Castle.

History
The tower, probably built soon after 1589, belonged to the Keith Earls Marischal. It was extended with artillery fortifications. It was bought by the Arbuthnotts after 1715. They built a new house, and the tower fell into disuse.

Structure
The castle had four storeys, and a garret; the wing was a later addition. The tower itself was round, and the addition, an unadorned house, was on the landward side.

About 1813 the castle was demolished to make way for harbour and other improvements.
