Old City Hall

Old City Hall was built to serve as the city hall of Philadelphia. According to the National Park Service, which runs the historic site, the building was the home of the U.S. Supreme Court from when construction was completed in 1791 until 1800, when the nation's capital moved to Washington, D.C. The city government and courts used the building until the completion of the current Philadelphia City Hall. It is a contributing property to Independence National Historical Park. The owner is the City of Philadelphia, which leases the building to the National Park Service.
