Stewart's Castle, also referred to as Castle Stewart or Stewart's Folly, was a mansion in Washington, D.C., located on the north side of Dupont Circle between Connecticut Avenue and Massachusetts Avenue. The house owed its various names to the original owner, Senator William Morris Stewart, the imposing, turreted facade, and its prominence in an area considered undesirable at the time of its construction. Designed by architect Adolf Cluss, the house was completed in 1873 but only stood for 28 years. It was badly damaged in a fire in 1879 but later repaired and rented to the Chinese Legation from 1886 to 1893. The house was sold to Senator William A. Clark, who razed it in 1901, intending to build a new residence. The plans never came to fruition. The site remained vacant for over 20 years until the construction of a commercial building, which still stands.
