Located directly under City Hall Park is the former City Hall subway station, the original southern terminal of the first service of the New York City Subway built by the Interborough Rapid Transit Company (IRT). Opened on October 27, 1904, this station beneath the public area in front of City Hall was designed to be the showpiece of the new subway. The platform and mezzanine feature Guastavino tile, skylights, colored glass tile work and brass chandeliers. Passenger service was discontinued on December 31, 1945, although the station is still used as a turning loop for trains.
