If you’ve ever wanted to visit CERN, the European Organization for Nuclear Research, this weekend is your chance. The buildings and grounds of CERN will be open to the public for its Open Days this Saturday and Sunday, 28-29 September.


Situated on the Swiss-French border, CERN is the birthplace of the World Wide Web and the location of the largest particle physics laboratory in the world. On 14 March 2012, scientists at CERN announced they had found evidence of the existence of the Higgs bosun particle, one of many major discoveries at the facility.

Activities are planned throughout the weekend at each of the CERN sites. Here are a few of the options: visit the CERN Control Center, the place from which the Large Hadron Collider (LHC) is controlled; take a virtual tour of the LHC experiments; see the cryogenic laboratory; watch a Fun with Physics show; see the “Universe of particles” presentation at CERN’s Globe exhibition site; see where CERN’s new linear accelerator is being built; or learn more about careers at CERN. Click here for a complete list of sites and events.

Don’t Forget: Bring an ID to enter CERN; you may also need your passport or ID card if you are crossing the border. Appropriate footwear is required; CERN does not permit high heels, open-toed shoes, or sandals.

Tickets and Access: Visits to surface sites do not require a reservation. Access to underground sites is allowed only for those holding a valid ticket. All tickets for the underground sites have been distributed, but because ticket holders can cancel their spots at any time, you can check the ticket site to see whether any spots have become available.
