Since its creation in 1954, CERN (European Organization for Nuclear Research) has been pushing back the frontiers of knowledge by exploring the mysteries of the universe, matter and fundamental particles.
Just a stone’s throw from the Pays de Gex, CERN opens its doors to you with a series of interactive experiments and captivating exhibitions at the Portail de la Science, a unique space for curious young and old alike.
Why discover CERN?
Dive into the heart of physics with the Science Portal
Thanks to immersive exhibitions, fun workshops and spectacular installations, you can discover :
- The origins of the universe: how it all began, from the birth of particles to the formation of galaxies.
- The Large Hadron Collider (LHC) : A fascinating view of this impressive machine that explores the secrets of particles.
- The impact of science on everyday life: from technologies such as the World Wide Web, invented at CERN, to advances in medical imaging.
This educational and fun venue also offers planetarium screenings, scientific demonstrations and areas dedicated to the very young to awaken their curiosity.
Guided tours and special activities
CERN also offers free guided tours of its emblematic facilities, subject to prior booking. You’ll have the chance to get up close to the laboratories, understand how the particle accelerators work and talk to the scientists involved in these world-class projects.
Throughout the year, events are organised at the Portail de la Science, including lectures, practical workshops and astronomical observation evenings. These events provide an opportunity to exchange ideas and gain a better understanding of the impact of fundamental research on our future.
Explore Pays de Gex with the Big Bang Passport
To enhance your visit to CERN, don’t miss the Big Bang Passport, which invites you to explore emblematic sites linked to science and nature in the Pays de Gex and around Geneva. This fun, interactive tour will help you understand the impact of CERN’s scientific research.
How does it work?
The Big Bang Passport is a free guide available online or in hard copy from the Pays de Gex tourist office. It features a nine-stop tour of the LHC (Large Hadron Collider), the world’s largest particle accelerator, which extends 27 kilometres underground.
At each stop, explanatory panels reveal the secrets of particle physics and CERN’s technological advances, while highlighting the local natural and cultural heritage. You can also scan QR codes to access interactive content and captivating videos.
