POTD: Abandon hope all ye who enter here

Today's photograph is from a collection of photographs of the Alabama State Hospital for the Insane's The Jemison Center, which was built in 1939 and housed patients until 1977, and found at The Daily Mail. 

     The caption for this particular photograph reads: "Due to overgrown plants little light is able to get into the abandoned building in the Tuscaloosa area where unexplained shadows have been glimpsed by visitors." Lots of other great photographs of the interior and some additional exterior shots at the link above. From a tactical perspective, you can see how hard it would be to spot someone inside the structure, while anyone entering from outside would be nicely silhouetted.
