I used to live 5 mins away from St. Margaret's hospital in Great Barr Birmingham. My friends and I would regularly go there at night and explore the underground tunnels and abandoned buildings and the night's always ended up the same way, screaming and running for our little lives.

My grandfather worked at Danvers State Hospital as a cook for many years (had loads of creepy stories about it), he used to joke that it was where he "served soup to nuts".
