Like most great inventions, the Jet d’Eau was actually created by accident. In 1886, the hydraulic factory, delivering water from the Rhône to the city's craftsmen and watchmakers, having to install a safety valve designed to relieve excess pressure by letting water escape, created a 30m jet towards the sky : the Jet d'Eau was born.
In 1891, Geneva City Council decided to turn the water jet into a tourist attraction and moved it to the end of the jetty in the port of Eaux-Vives. Connected to the drinking water network, the second water jet was born - climbing to 90m.
In 1951, new waterworks built to use the lake allowed the jet to reach 140m.
Did you know the Jet d'Eau had a beauty secret : The secret to propelling such a huge torrent of water into the sky is in the pipes. A special tailpipe projects a tube of water measuring 16m in diameter and another pipe fills it with millions of air bubbles to create its magnificent white colour.
On 25 August, 2016, the fountain celebrated its 125th anniversary at its present location.
