Parc de la Perle du Lac, Public park at Lake Geneva shores, Switzerland

Parc de la Perle du Lac is a public park on the shores of Lake Geneva with wide pathways, gardens, and relaxation areas. Mature trees and colorful flowerbeds frame the landscape, while seating areas invite visitors to linger.

The park's name comes from the wife of Hans Wilsdorf, founder of Rolex, who on visiting is said to have exclaimed "Ceci est la perle du lac!". The sources give no founding date for the park itself; the Florentine-style building on its grounds, now the Musée d'histoire des sciences, was built in 1829. The park belongs to a chain of contiguous lakeside parks on the right bank of Lake Geneva, after the Pâquis district.

The park's name comes from an exclamation attributed to the wife of Hans Wilsdorf, founder of Rolex, on seeing the spot: "Ceci est la perle du lac!" A restaurant owned by the City of Geneva serves French haute cuisine, and its terrace looks out over the lake, the Jet d'eau and, in clear weather, Mont Blanc.

The grounds are accessible through multiple entrances connected to public transportation and clearly marked. During summer, deck chairs are placed throughout, making it easy to find a spot for walking, sitting, or picnicking.

The park's name comes from a remark attributed to the wife of Hans Wilsdorf, founder of Rolex, who is said to have exclaimed "Ceci est la perle du lac!" while visiting. The Florentine-style building of 1829 now holds the Musée d'histoire des sciences.
