"This haunted island was once a home for people dying from the bubonic plague, and it later housed a mental institution in the early 1900s. In the 1930s, rumors persisted that a doctor performed experiments on patients there. Now, the island is abandoned, but some of the local tour companies — Classic Boats Venice and Venice Tour By Boat — offer excursions." - Travel + Leisure Editors
