Current COVID-19 conditions for CERN visitors

[updated 8 January 2022]

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 is currently under COVID Level 4 which means that:

  • The Microcosm exhibition and CERN shop (at CERN reception) are open with strict sanitary measures (see below) in place. There may be wait times due to the influx of visitors. We ask you to be understanding.
    Groups of 12 visitors and more planning to visit Microcosm are requested to inform visits service in advance given the limited capacity of the exhibition.
  • Public events in the Globe of Science and Innovation will take place with strict sanitary measures (see below) in place.

In the meantime,

  • The Universe of Particles exhibition (in the Globe) remains closed until further notice
  • All individual guided tours are unavailable until further notice
  • All group guided tours scheduled to take place before April 2022 have been cancelled. We are not able to accept requests for guided tours taking place before September 2022.

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 A swiss/european QR code COVID certificate certifying vaccination or recovery from COVID-19 along with picture ID is required to access Microcosm and events in the Globe for all visitors aged 16 and over.

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.
