Current COVID-19 conditions for CERN visitors

[updated 10 September 2021]

IMPORTANT CHANGE: COVID CERTIFICATE IS NOW REQUIRED - CHECK BELOW

The health and safety of all those who visit and/or work at CERN is paramount. CERN has adapted many activities to the evolution of the COVID-19 pandemic.

Thus since 1 June 2021, CERN has implemented a new four-level COVID-19 scale, determining conditions for several measures, including access for visitors. The level in force at any given time is determined by the incidence rate in the local area, and a qualitative assessment by CERN taking into account, among other parameters, the number of confirmed cases at CERN and vaccination status in the local area.

CERN COVID Level 2

CERN is currently under COVID Level 2 which means that:

In the meantime,

  • The Universe of Particles exhibition (in the Globe) remains closed until further notice
  • All group guided tours scheduled to take place before November 2021 have been cancelled. We are not able to accept requests for guided tours taking place before November 2021.

Sanitary measures (activity-specific measures are communicated on site)

No entrance Access of visitors to CERN sites is not allowed in situations of
  • contact in the last 14 days with a person that has tested positive for COVID-19 or is suspected to be infected by coronavirus
  • a suspected or confirmed case of COVID-19
COVID Certificate mandatory Since Monday 13 September, a COVID certificate valid in Switzerland with picture ID is required to access Microcosm, guided tours and events in the Globe for all visitors aged 16 and over. This follows a decision by Swiss Federal Council to extend COVID certificate usage and which CERN has decided to implement as well.
Only QR certificates validated by the swiss Covid Certificate Check app will be accepted (click on the link to download the app and test your own certificate).
A valid picture ID will be required to check certificate holder's identity.
Mandatory mask wearing Mandatory wearing of type 1 surgical mask (will be provided if needed), even with COVID certificate.
Sanitizing gel Mandatory disinfection with hand sanitizing gel before entering the venues
Valid ID Globe Public Events will be accessible upon prior registration with full identification of the person that is registering
COVID Tracing App Visitors are encouraged to install a tracing application such as SwissCOVID (CH) or TousAntiCOVID (FR) on their smartphones

​Any changes to these measures will be published on this page. 

We thank you for your understanding and look forward to welcoming you gradually back to CERN.

Don't forget that you can still discover CERN online or attend a virtual tour or talk.
