In 1922, a mental hospital was opened on Poveglia. Local legend says that one doctor at the hospital tortured and killed many of his patients, butchering them horribly only to later die by falling from, or possibly being thrown off of, its bell tower. The hospital closed in 1968, and the ruins are still there, slowly being reclaimed by greenery. And while it is professed to be a former retirement home, evidence that it housed mental patients is still evident.
With a past like this, it’s not surprising that Poveglia is believed to be haunted, attracting the attention of ghost hunters and paranormal investigators.
Elsewhere in the lagoon, the remains of the Insane Asylum on San Servolo Island are preserved as a museum dedicated to the history of Venice’s plague islands and asylums.
Poveglia remains for now strictly off-limits to visitors.[AtlasObscura]
A quarantine station, a dumping ground for plague victims, more recently a mental hospital — the tiny island of Poveglia in the Venice Lagoon has served many unpleasant purposes over the years, but today it stands empty, a crumbling collection of abandoned buildings and weeds run riot just two miles from the glittering palaces of the Grand Canal. Legends and rumors about Poveglia are nearly as pervasive as the weeds, and they read like a horror story: that so many people were burned and buried there during the black plague that the soil is 50% human ash; that local fishermen give the island a wide berth for fear of netting the wave-polished bones of ancestors; that the psychiatrist who ran the mental hospital was a butcher and torturer who went mad from guilt and threw himself from the island’s belltower, only to survive the fall and be strangled by a “ghostly mist” that emerged from the ground.[MentalFloss]
