Call it a sanitarium, asylum, or a hospital, it's a great place to create haunted adventures in any campaign. This sanitarium has three stories, a basement and two wings, not to mention the creepy cabin and mausoleum on the sanitarium grounds.
These maps can be used anywhere, but are also compatable with the adventure, Lamp's Light Sanitarium by Matt Corley with Donathin Frye (no association). I encourage you to take a look at this very well-written adventure.
