DC SUPERIOR COURTS
History

Located north of Pennsylvania Avenue, between the Capitol and the White House, Judiciary Square is adjacent to the monumental core of Washington, DC. This northwest DC neighborhood is mostly occupied by various federal and municipal courthouses and office buildings, among them: the Superior Court of the District of Columbia, the H. Carl Moultrie Courthouse, the Old DC Courthouse (Old City Hall), the E. Barrett Prettyman Building, the United States Court of Appeals for the Armed Forces, the United States Court of Appeals for Veterans Claims, and the United States Tax Court. Court Building A (the former Police Court, dating from 1936) and Court Building B (the former Municipal Court, dating from 1938) are the work of Nathan C. Wyeth, DC Municipal Architect from 1934 to 1946, who designed the limestone and granite buildings in a neo-classical style.
