The Île de Peilz (French pronunciation: [il də pɛ]; Peilz Island) is a minute island at the eastern end of Lake Geneva in Switzerland, close to Villeneuve, Vaud. Measuring a few dozen square meters and featuring a monumental London plane tree, it is the smallest and the only natural island in the lake.
Its history is unclear, but it was built up in its current form in the 18th century. It has left cultural traces in the works of Lord Byron and Hans Christian Andersen, as well as in local legend. More recently, it has become a popular subject of social media photographs.
