A house with several lives
The Garrison is associated with Captain James Crawford of the revenue cutter Royal George. The local heritage trail dates its beginnings to about 1745, although other accounts place the surviving house later in the eighteenth century. The exact early building sequence remains uncertain. George Boyle, fourth Earl of Glasgow, bought and enlarged it in 1819; it later passed to the Bute estate.
Gothic house and enclosed grounds
Historic Environment Scotland describes a long, low mansion with battlements, gables and Gothic finials. The listing includes the walled garden and gateways, whose pointed arches extend the architectural character beyond the house itself. Those enclosing elements are part of the historic composition, not incidental boundaries.
Restoration and reuse
The house’s changing functions included a hydropathic establishment, wartime hospital accommodation and local government premises. Fire severely damaged it in 2001, followed by restoration and reopening in 2008. The Category B listing recognises its architectural interest; it does not establish current opening hours or access to every part of the property.
