The Villa Diodati is a manor in Cologny close to Lake Geneva. It is most famous for having been the summer residence of Lord Byron, Mary Shelley, Percy Shelley, John Polidori and others in 1816, where the basis for the classical horror stories Frankenstein and The Vampyre were laid.
Originally called the Villa Belle Rive, Byron named it the Villa Diodati after the family that owned it. The family was distantly related to Italian translator Giovanni Diodati, uncle of Charles Diodati, the close friend of poet John Milton. Despite the presence of a plaque at the Villa heralding a supposed visit of Milton in 1638, in fact the villa was not built until 1710, long after Milton’s death.
