Floors Castle, on the western outskirts of Kelso, south-east Scotland, is the seat of the Duke of Roxburghe. Despite its name it is a country house rather than a fortress. It was built in the 1720s by the architect William Adam for the 1st Duke, possibly incorporating an earlier tower house. In the 19th century it was embellished with turrets and battlements by William Playfair for the 6th Duke. Floors has the common 18th-century layout of a main block with two symmetrical service wings.
