Which Fictional Place Would Make the Best Haunted House?

Halloween is just a few short weeks away and with all the horror movies, candy, and costumes, there also comes one of our favorite fall traditions—the haunted house. Recently, a list of the ten most terrifying haunted houses was posted on Yahoo! Travel. Former asylums, prisons, and the old standard—cornfields—were all represented on the list.

There are certainly a lot of creepy villains out there in the mystery world, and a lot of creepy places for those villains to take you. It got us to thinking, which fictional location would you choose as the best haunted house? What Big Bads would you choose to work it (on the guarantee that they can't kill/eat/torture the customers)?
