2. Poveglia, Italy
Unlike the other locations on this list, Poveglia isn’t off-limits to travellers. On the contrary, the Italian government is actually willing to rent the island so that the expansion of land will not sit unused as it is now. The reason why it has been completely abandoned is simple: it is considered to be one of the most haunted places on earth. The island has had a fort, been a checkpoint for ships, been an isolation home to plague patients and had a psychiatric facility until 1968. The departed souls of those plague patients and mentally deranged individuals are still rumoured to be roaming around the island.
