Lainshaw Castle

Lainshaw Castle was a 15th century castle about 1.0 mile (1.6 km) south-west of Stewarton, East Ayrshire, Scotland, to the north of Annick Water.

William Cunninghame, one of the tobacco lords, bought it in 1779 from Sir Walter Montgomerie-Cunninghame, 10th Laird of Lainshaw, who had been impoverished by the American War of Independence.

Inheriting the estate upon his father's death in 1799, his third son, William, began an extensive program of modernising the structure in the classical style;[4] in 1824 a Tudor-Gothic extension was added.

[1] Lainshaw Castle was described by Timothy Pont in 1608 as 'a stronge old Dunijon'.

The surviving walls have been pierced by various doorway, providing access to later structural additions, with some subsequently being blocked.
