Haunted Island in Italy

I forget the name of the island, but could this be the one that the guys from Ghost Adventures investigated years ago? The one where Zak was possessed, I think. This is the problem with Unbelievable Facts. They don't even have their facts. "There's an island in Italy-" WHERE in Italy? What's the island name? How is it haunted? Some aspects you really need to consider before calling yourself a fact site.
