Top 10 "Most Haunted" Places in the World

The Contaminated has a pretty decent article highlighting what it considers to be 10 of the most haunted places in the world.

Now, who knew the Whitehouse was considered one of the most haunted places in the world?

Edinburgh Castle in Scotland seems to top the list at #1.

My only real problem with this article (and it's minor) is that it seems to focus primarly on US or UK hauntings.  What about the rest of the world? Aren't there hauntings in Canada, Germany, France?

In any event, it's an interesting short read.
