New York's City Hall Subway station

Still, although it's not open to the general public, there's a way in-the-know New York subway riders can still see this famous and beautiful architectural glimpse at the city's past. The 6 train used to make all passengers leave the train at the Brooklyn Bridge stop, but no longer.

If you have a little extra time, you can stay on the train and view the City Hall Station as the train makes its turnaround.
