Located on the banks of the Tweed, the home of the dukes of Roxburghe was designed in 1721 by William Adam and remodeled in the mid-19th century by William Playfair. Part of the castle contains superb French and English furniture, porcelain, tapestries, and paintings by Gainsborough, Reynolds, and Canaletto.
