City Hall is the New York City Subway station containing the historic 1904 station house and original loop platform.
The station was built as the southern terminal of the original Interborough Rapid Transit subway. Its design included elegant Guastavino tile vaults, skylights, brass fixtures, and curved platforms intended for the early IRT trains. The station opened with the first subway line in 1904.
City Hall’s sharply curved platform became unsuitable as trains grew longer and subway operations changed. The station closed to regular passenger service in 1945, although the tracks remain part of the active route and trains pass through the loop.
Today, riders generally see the station from a downtown 6 train as it turns through the loop. The historic space is not an ordinary open station, so it is often confused with nearby Bowling Green or Brooklyn Bridge–City Hall. Special tours have allowed visitors to view the preserved interior.
