Introduction: Discover the Observatory of Geneva
Nestled in the tranquil suburb of Versoix, just north of Geneva, the Observatory of Geneva (Observatoire de Genève) stands as a testament to centuries of astronomical discovery and scientific excellence. Established in 1772, the observatory has evolved from a pioneering center for timekeeping and navigation into a state-of-the-art facility renowned for groundbreaking research—most famously, the Nobel Prize-winning discovery of 51 Pegasi b, the first exoplanet orbiting a sun-like star (Observatory of Geneva website, SwissInfo). Today, visitors can experience a dynamic blend of heritage and innovation through guided tours, public events, and educational workshops.
This comprehensive guide equips you with everything needed to plan your visit: opening hours, ticketing, accessibility, highlights of scientific achievements, and suggestions for nearby attractions. For the latest scheduling and booking details, consult the Observatory of Geneva’s official website.

Historical Overview
Foundations and Legacy
Founded in 1772, the Observatory of Geneva initially focused on astronomical observations and providing chronometric certification vital to Geneva’s famed watchmaking industry (Observatoire Chronométrique). Under the leadership of figures like Jean-André Deluc and Jacques-André Mallet, the observatory became integral to both scientific advancement and economic growth.
Modern Era and Relocation
By the mid-20th century, urban expansion and light pollution necessitated the observatory’s move from central Geneva to Versoix in 1966. The new site enabled the installation of larger telescopes and modern laboratories, transforming the observatory into a hub of international research. Today, it continues to contribute to major missions with the European Southern Observatory (ESO), European Space Agency (ESA), and NASA (UNIGE Astrophysics Master).
