The long since abandoned City Hall subway stop.
A brief departure from my normal nocturnal ramblings: The next time you find yourself downtown with some time to kill, hop on the downtown 6 train and take it to the last stop on the line, the Brookyn Bridge station. But instead of getting off, stay on the train as it loops around to the uptown track to begin its trip back north through East Harlem and the Bronx. Keep your eyes open as you pass through the long since abandoned City Hall stop, which is one of the city's lost forgotten treasures. Originally built in 1904, the station was closed in 1945, primarily because not too many people used the station and the loop created an unsafe gap when the train stopped at the station platform.
Notwithstanding the obvious safety issues that would come with having a train station directly under City Hall, one can only hope that the station is one day put back into active service.
