Damn, but City Hall Station is beautiful, even the limited views you have of it when you ride an out-of-service #6 train past the line's terminus at Brooklyn Bridge.
The startling thing about it, and what I never would have guessed from the photos I've seen, is how small and constricted it is. I had always pictured it as a place of cavernous grandeur. Grand it is, even now. Cavernous it is not.
