It's euhm... an underground government funded facility. :P
you're terrible explaining things :P
Granted...Fell hasn't even given us much to work with there...aside from it's underground.
I imagine it's in a large, underground cave, either natural or man made. The students actually don't know where it is. It was built secretly so as to..you know, super villains wouldn't find it. Probably has some fancy gardens or something on the outside, sort of like the school grounds. At least, that's how I'm imagining it xP
