The Jet d’Eau isn’t just a feat of engineering, but Geneva’s signature landmark, visible from nearly any point along the lakeshore. It propels 500 liters of water per second up to 140 meters into the air. Originally built as a pressure release valve in the 19th century, it soon became a symbol of the city. The fountain is especially striking in the evening when it’s beautifully illuminated.

What to see
- Harbourwide views from the Jetée des Eaux-Vives toward the quays, Old Town and Pont du Mont-Blanc.
- A counter-view from Bains des Pâquis on the opposite shore.

History
The first jet appeared in 1886 as a safety release at the Coulouvrenière hydraulic plant – a utilitarian ~30 m plume. In 1891, a decorative fountain was installed at Eaux-Vives in the harbour, reaching ~90 m.
An autonomous pumping station in 1951 switched to lake water and raised the height to 140 m. Since then the Jet d’Eau has been Geneva’s signature sight; with LED lighting it often marks international causes in colour.
