The Jet d'Eau is a large fountain in Geneva, Switzerland, and is one of the city's most famous landmarks, as well as one of the largest fountains in the world. Situated at the point where Lake Geneva empties into the Rhone River, it is visible throughout the city and from the air, even when flying over Geneva at an altitude of 10 km. In 1891, the City of Geneva decided to install the Jet d’Eau where it is today, on the Rade, together with electric lighting. But it is only since 1930 that it was permanently lit.
