North Lanarkshire, Scotland: Cambusnethan Priory
This Gothic Revival priory, designed by James Gillespie Graham in 1820 and featuring turrets at each corner, is—perhaps surprisingly—one of the better remaining examples of 19th-century neo-Gothic architecture in Scotland. Considering it has not been occupied since the 1980s, the building has fallen into severe disrepair. It’s listed as “at-risk” by the Scottish Civic Trust.
