TheVilla Diodati is a mansion in the village ofCologny nearLake Geneva inSwitzerland, notable becauseLord Byron rented it and stayed there withDr. John Polidori in the summer of 1816.Mary Shelley,Percy Bysshe Shelley, and Mary’s stepsisterClaire Clairmont, who had rented a house nearby, were frequent visitors. Because of poor weather, in June 1816 the group famously spent three days together inside the house creating stories to tell each other, two of which were developed into landmark works of theGothic horror genre:Frankenstein by Mary Shelley andThe Vampyre, the first modernvampire story, by Polidori.
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 translatorGiovanni Diodati, uncle ofCharles Diodati, the close friend of poetJohn 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.[1]

Lord Byron rented the villa from 10 June to 1 November 1816.[2] The scandal of his separation fromhis wife, rumours of an affair withhis half-sister, and ever-increasing debt, had forced him to leave England, never to return, in April of that year.[3] Byron arrived atLake Geneva in May where he met and befriended the poetPercy Bysshe Shelley who was travelling with his future wife Mary Godwin (now better known asMary Shelley). Byron settled at the Villa Diodati with his personal physician,John William Polidori, and Shelley rented a smaller house called "Maison Chapuis" on the waterfront nearby. The group was also joined by Mary's stepsister,Claire Clairmont, with whom Byron had had an affair in London.[4][5]
The weather was unseasonably cold and stormy, and Mary Shelley later described the "incessant rain" of that "wet, ungenial summer".[6][note 1] When the rain kept them indoors at the Villa Diodati over three days in June, the five turned to reading fantastical stories, includingFantasmagoriana, and then devising their own tales. Mary Shelley wrote the first draft of what would becomeFrankenstein, or The Modern Prometheus. She was just 18 years old at the time. Polidori was inspired by a fragmentary story of Byron's,Fragment of a Novel, to produceThe Vampyre, the progenitor of theRomanticvampire genre.[8][9]

Byron's story fragment was published as a postscript toMazeppa; he also wrote the third canto ofChilde Harold.
After Byron's death, the Villa Diodati soon became a place of pilgrimage for devotees of Byron, and ofRomanticism. The French writerHonoré de Balzac, who had become obsessed with the villa, had one of the characters in his 1836 novelAlbert Savarus remark that the Villa Diodati is "now visited by everybody, just likeCoppet andFerney" (the homes ofMadame de Staël andVoltaire respectively).[10]
The villa has remained in private ownership. In 1945, the French artistBalthus moved into the property for a short period.[11] The columnistTaki has written that when he visited the Villa Diodati in 1963 with the Belgian tennis playerPhilippe Washer it was then owned by the latter's family.[12] However, theNew York Times has reported that, as of 2011, the villa had been split up into "luxury apartments".[5]
