Poveglia is an island known as one of the most mysterious and creepy places in the world. It all started during the Roman Empire when the island was used to home victims of the plague. Later, during the medieval era, when the plague returned, the island once again became a home to thousands of deadly sick people. A terrible amount of people were dumped into the ground, buried in the same graves and even burned. People say that the land became so affected by the burned and rotten human corpses, its soil is now 50% composed of human ash. Then, back in 1922, they opened a mental hospital here. It is safe to say that it did not affect the patients in a positive way, since the island already had a truly creepy vibe to it. Now, you can still find washed up human bones on the island’s shore due to the horrific amount of humans killed there. With many people saying this place is haunted, no wonder this island is illegal to visit, and we’re not sure anyone would want to go there.
