One of Geneva’s most famous and beautiful symbols arrived by accident. The fountain was originally just a pressure release from a hydro-power plant on the Rhône River, but people loved it so much that the city installed a permanent fountain on the lake. The Jet d’Eau (literally, “water jet”) releases a plume of water 140 meters into the air and it’s spectacularly lit at night. You can see it from pretty much anywhere along the waterfront but beware that if you get close you’ll be soaked! But what better relief on a hot day?
