But my favorite has always been the old insane asylum:
Here's the front of the building. This part is still used--they turned it into a museum. Back in the fall of 2009 I crept around and took pictures of the place, which I am posting for you today in honor of Halloween. (My apologies for not being a better photographer.)
And pictures of the totally abandoned wings. Some part of one of the floors (the first, I think) was turned into art studios, but vast expanses of this building sit totally untouched. I don't know how often people go inside, but if you don't work here, it's nearly impossible to get a look at the old rooms. One entire half of the building (which is huge and done in the Kirkbride style) goes completely unused as far as I'm aware.
They didn't put names on the gravestones, just numbers.
Right next to this cemetery is the tuberculosis ward--it is even more run-down than the main building. They don't use it for anything.
People broke in here all the time--so they went so far as to put barbed wire on top of the fence. If you COULD get past the fence (and people used to all the time) you'd see creepy paintings on the walls when it was used as a daycare. I think there's an old piano in there, too. Now, there's no barbed wire. They've cleared out the courtyard and cemented all the windows and all the doors. No getting inside anymore.
Some pictures I managed to grab through a window:
