Jet d'Eau is a landmark fountain located in the city of Geneva, Switzerland. It is one of the most popular tourist attractions in the city and is a symbol of Geneva's identity.

The fountain was first built in 1886 as a functional feature to regulate the pressure of a hydraulic power plant. However, its beauty and spectacular height of 140 meters made it a major attraction, and it was later redesigned as a tourist attraction.

The Jet d'Eau is located at the end of the Geneva Lake, on a pier in the city's harbor. The fountain is powered by a hydraulic system that pumps water at a rate of 500 liters per second. The water is then propelled through a nozzle at a speed of 200 kilometers per hour, creating the iconic water column.

The fountain operates throughout the year, with different schedules depending on the season. During the summer months, the fountain operates for longer hours and is illuminated at night, providing a spectacular sight.

The Jet d'Eau is not just a landmark attraction, but also serves as a useful guide for those navigating the city. Its position at the end of the lake makes it visible from many parts of the city, and visitors often use it as a reference point when exploring Geneva.
