The Large Hadron Collider (LHC) is the world's largest particle accelerator. Its 27 km ring is buried 100 metres below the French and Geneva countryside.
The LHC was designed to explore the biggest mysteries of our Universe... What happened after the Big Bang? How did our Universe evolve? These are just some of the many questions being investigated.
The Passport to the Big Bang is an interactive circuit through which you can explore this giant machine. The Passport is available in tourist offices and town halls in the Pays de Gex and the Canton of Geneva, as well as from the CERN Reception.
This project has been selected for inclusion in the European Territorial Co-operation programme INTERREG IV A France-Switzerland 2007-2013.
