Venice is famous for its lagoons; for streets that you need to use bridges or boat to cross. However, just off its coast is a tiny island that is definitely haunted. That island is Poveglia. The townsfolk constructed the island as a quarantine outpost for Venetians who were living with the plague. According to legend, 50% of the soil is actually human remains. In its more recent past, a sanitorium was also opened on the island. Although it’s now illegal for visitors to set foot on the island, Poveglia can still be seen from the shore.
