CERN is the world’s biggest laboratory for particle physics. More than 10 000 physicists, engineers and technicians from all over the world come to CERN to advance our understanding of the universe.

On 14 and 15 September 2019, CERN will open its doors to you and take you on a journey through the world of particle physics.

Meet the scientists behind the discoveries, travel 100 metres underground to visit the LHC and the gigantic caverns housing particle detectors, step into the control rooms from where these machines are operated, learn how the gigantic datasets are analysed by a worldwide network of computers, take a tour of hi-tech labs and fabrication plants, participate in hands-on activities for the whole family, and much more.

The CERN Open Days app will provide you with practical information and show you interesting visit points, possible parking and the places where you can grab some food or beverages. With an accurate map, you will never get lost.

Let the CERN Open Days app guide you in your immersion into particle physics!
