buffalo state hospital - completed in 1895
hudson river state hospital - completed in 1871
and lastly, my favorite and probably most famous:
danvers state hospital - completed 1878
there is a movie called 'session 9' that was filmed inside danvers. it's super cool/creepy to see the inside of the hospital. it's very prison-like. there are hallways & stairways separated by ceiling to floor chain link fencing. one side is for staff, the other for patients.
here are some interior pictures
there is NO amount of money that you could pay me to walk down that underground brick hallway alone. but sadly, if a certain guy looked at me with his BIG BLUE EYES and said "if you go down that hallway, in the dark, by yourself... i'll spend the next 24 hours with you".... i'd go. and i'd go smiling... but with a bit of pee running down my leg.
could you do it?!
