Villa de Vecchi: The Abandoned Haunted Mansion of Cortenova, Italy.

Since its construction in the 1850s, the mansion has reportedly been the site of a string of tragedies, including the murder of the family of the Italian count who built it, as well as the count’s suicide. It’s also said that everyone’s favorite occultist, Aleister Crowley, visited in the 1920s, leading to a succession of satanic rituals and orgies. By the 1960s, the mansion was abandoned, and since then both nature and vandals have helped the house fall into dangerous decay. The only permanent residents are said to be a small army of ghosts, who especially love to play the mansion’s piano at night—even though it’s long since been smashed to bits.
