The Old Brick Capitol in Washington, D.C., served as the temporary meeting place of the Congress of the United States from 1815 to 1819, while the Capitol Building was rebuilt after the burning of Washington.
"Old Brick" served as a private school, a boarding house, and, during the American Civil War, a prison known as the Old Capitol Prison. It was demolished in 1929, and its site is now occupied by the U.S. Supreme Court building.
