Drumlanrig's Tower was originally a 16th century stone L-plan tower house, founded by the Douglas family. Of three storeys and a garret, the basement in the main block was vaulted and the hall stood on the first floor. Standing inside a late 12th or early 13th century ditch, at least two splayed gun-loops guarded the entrance in the re-entrant angle. In 1701-2 the Queensberry family extended and reconstructed the tower, when they infilled the angle to square off the block but much of the original L-plan layout still survives. Now a large comfortable town house, the floors in the wing match those in the main block and both are reached via a corridor from the spiral stair. Nearby is Hawick Motte and 16 miles south is Hermitage Castle.
