The Hellmouth was both a Font of Evil and a Weirdness Magnet. I haven't seen the idea of locations that are Weirdness Magnets in-game, but it seems to fit the setting, and probably a few others. Depending on the Dungeon (good idea, Anthony) and the GM, it may be that the genius loci is a Weirdness Magnet as well as a Font or Sinkhole of Evil, or that the location is, or it may be that this particular Dungeon is only one or the other.

Could also be the way that living Weirdness Magnets and beings with similar disadvantages (Demon Magnet? Evil Sanctity Enhancer?) are handled in-setting: choosing or compelled to take up residence somewhere away from civilization, where the problems and strangeness that they bring cannot trouble their neighbors.

EDIT: Now I feel kind of tempted to design a dungeon on this theme. If I do, don't expect it to happen fast.

Also, I think Paranormal Waste Repository may be somewhat relevant to this discussion.
