Horsburgh Castle

Horsburgh Castle is a ruined 16th-century L-plan tower house situated on a hilltop overlooking the River Tweed near Peebles in the Scottish Borders. Built of harled whinstone rubble by the Horsburgh family, the castle originally featured a vaulted ground floor and defensive slit windows, measuring approximately 31 by 33 feet. A scheduled monument, the castle served as the ancestral seat of the Horsburghs from at least 1479 and functioned as part of a beacon chain alerting the region to raiders, leaving a lasting imprint on the landscape that inspired artist J.M.W. Turner's 1834 sketch.
