Open Days 2027 Logo

In September 2027, CERN will once again open its doors to the public during the Long Shutdown (LS3), a period dedicated to upgrading the accelerator complex and preparing for the High-Luminosity Large Hadron Collider (HL-LHC) era.

We wanted the Open Days 2027 logo to highlight this important stage in CERN’s future. The design is inspired by the High-Luminosity LHC, which will increase the number of collisions.

The logo’s primary colour palette consists of blue and yellow. However, we have also developed alternative colour variations for different applications and communication materials, such as email signatures.

We prepared both English and French versions of the logo.
