Explore the state of Delaware
Completed in 1791. The Old State House is one of the oldest state-house buildings in the United States, serving as the home of Delaware's legislature until 1933 when the General Assembly moved to larger quarters in Legislative Hall. The Venerable structure now appears as it would have in the late 1700s during the United States critical early years as a nation. It features a courtroom, governor's and county offices and chambers for the state's Senate and House of Representatives. The building is situated on Dover's historic Green, a public area designated by William Penn in 1683.
