Old City Hall, Manhattan
The best-known disused station in town is Old City Hall. The first-ever subway ride in New York City departed from here in 1904. Designed by architects Heins & LaFarge, the terminal featured elegant chandeliers, skylights and vaulted tile ceilings created by artisan Rafael Guastavino. It was closed in 1945, mostly because it was made without the practicalities of larger trains in mind, rendering it one of the least-used stations in Manhattan.
Today, Old City Hall is not totally off-limits – you can explore it by booking a tour with the New York Transit Museum. However, they only run sporadically throughout the year, and you must be a member of the museum to claim a spot.
