4 Best Sights in Rive Gauche (Left Bank), Geneva

The city's landmark fountain, which shoots 132 gallons of water—the equivalent of four standard bathtubs—459 feet into the air every second at 125 mph, can be seen throughout downtown. The parks and promenades around the lake offer the opportunity to see it from almost 360 degrees, and a wooden walkway on the pier at dock Gustave-Ador makes it easier to view up close.

Archaeologists found multiple layers of history underneath the Cathédrale St-Pierre when its foundations began to falter in 1976. Excavations have so far yielded remnants of two 4th-century Christian sanctuaries, mosaic floors from the late Roman Empire, three early churches, and an 11th-century crypt. The first Romanesque cathedral on the site was built in 1000. Audio guides in English and careful lighting help navigate the (reinforced) underground maze that remains.

Large, evocative wildlife dioramas complete with sound effects cover most major animal types at this spacious museum. Large quantities of fossils, gigantic crystals, precious stones, and a case full of polyhedrons ensure that the place is always swarming with local school groups. Swiss geology, the history of the solar system, and thematic temporary exhibits round out the collection; most labels are in French. The museum is a short walk away on the outskirts of the Vieille Ville.

This sloping park, once the private grounds of an 18th-century villa overlooking the lake, is filled with remarkable plant life, including a collection of cedar trees more than 200 years old, Geneva's biggest rose garden, orangeries, an alpine garden, and a collection of brightly flowering rhododendrons. The Orangerie and the Théâtre de Verdure stage performances and open-air concerts through the summer months.
