The Cannon House Office Building, often called the "Old House Office Building", completed in 1908, is the oldest office building of the United States Congress in Washington, D.C. A significant example of the Beaux-Arts style of architecture, it occupies a site south of the United States Capitol bounded by Independence Avenue, First Street, New Jersey Avenue, and C Street S.E. In 1962 the building was named for former Speaker of the United States House of Representatives Joseph Gurney Cannon.
