CERN Open Days 2019 | 14–15 September

On 14 and 15 September 2019, CERN will open its doors to the public for two special days at the heart of one of the world’s largest particle-physics laboratories.

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. We are now in Long Shutdown 2.

The 2019 Open Days will give visitors the chance to discover our facilities, both underground and on the surface. With free admission to debates, film screenings, theatre performances, experimental workshops and dozens of visit points spread all over the site, we will take you to the heart of our Laboratory, in direct contact with the science of today and tomorrow.

The Open Days are a unique opportunity to visit CERN, don’t miss it.
