This tiny island just off the Italian coast could well be a dammed place as it has such a gruesome and disturbing history. It was used in the 18th century as a quarantine station for these suffering from the plague. In fact, most who were sent there were simply left to die in the thousands, neglected and forgotten by society. It is believed that, over just a few decades, well over 100,000 people died and were buried all over the island in various massive pits.
Eventually, a mental asylum was built on the island and soon rumors were going around that the head doctor was carrying out grisly experimental brain surgery on the patients without the authorities knowing. Some believe that the ghosts of these he butchered came back to haunt him and he committed suicide in order to try and escape them.
Many visitors have since claimed that you can still hear cries in the long-abandoned mental hospital. Because of this, no one now dares to live on this island.
