The CERN Open Days have become a regular feature of the period that we call the “long shutdown” during which our accelerators stop for around two years, to benefit from upgrades and renovation work. And Long Shutdown 2 has just started.

Similar to the 2013 edition, the 2019 Open Days will give people the chance to discover our facilities both underground and on the surface**. Debates, film screenings, theatre performances, experimental workshops and, of course, dozens of visit points spread all over the site will take you to the heart of our Laboratory, in direct contact with the science of today and tomorrow.

The programme of the event and all practical information will be communicated in 2019. For now, save the dates of this exceptional event and come and visit CERN.

* Admission is free of charge for all audiences.
** Some sites may have age and access restrictions.
