Curse of the cranium
Poveglia Island in Venice, Italy, looks picturesque, surrounded by sparkling azure water. But the place has a spine-chilling reputation - it is known as the world’s most haunted island. Once a dumping ground for plague victims, many people thought to have the disease in the 17th and 18th centuries were forcibly taken to the island to die. It is estimated that 10,000 bodies are buried there. In the 1920s, an asylum opened on the island. A mad doctor was rumoured to have carried out horrific illegal experiments on patients, including lobotomies without anaesthetic, before finally killing himself by jumping from the asylum’s tower. Many locals refuse to set foot on the island, believing it is cursed.
