Guess the Dungeon #6

Not a dungeon at all today, but a building.  Can anybody tell me the name of this place?  If you don't know the adventure you should still be able to guess the basic plot simply by looking at the map.

Here's my own map for today.  This is one I've been toying with turning in for this year's One Page Dungeon Contest.  The doors are enchanted and don't always lead where you expect them to, but if you know how to use them you should be relatively safe.
