Geneva is Switzerland's French-speaking city and is the second largest in the country. With sights such as the Jet d'Eau, the Cathedrale St-Pierre, the Bourg-de-Four square, and the Bodmer Foundation, this cosmopolitan city is also an important financial and diplomatic global center. The refined suburb of Cologny comprises beautiful residential villas as well as luxury estates. Located on Lake Geneva, further sub-sections, or villages, include Pres-de-la-Gradelle, Rampe-de-Cologny, Ruth-Nant d'Argent, Saint-Paul, and Stade-de-Frontenex.
