Poveglia is a small island located between Venice and Lido in the Venetian Lagoon, northern Italy. According to legend, during Roman times it was used to isolate thousands of plague victims, and during the three occasions when the Black Death spread through Europe, the island was effectively used as a lazaretto and plague pit – it was considered an efficient way of keeping the infected people separated from the healthy. According to this version, over 160,000 people died on the island throughout its history. Another legend surrounds a building erected in 1922 on the island, which was used for various purposes, including usage as a mental hospital. The legend states that a particular mental health doctor tortured and butchered many of the patients, before going "mad" and jumping to his death from the bell tower. According to that same legend, he survived the fall, but was 'strangled by a mist that came up from the ground'. Its ruins remain to this day.
