CERN's usual scientific exhibition (it was named "microcosm") is temporarily closed, awaiting the big constructions to finish in that area, and a new outreach experience centre to open (Summer 2023?).

In the mean time, we can visit CERN's Globe of Science and Innovation, featuring a more broad-public exhibition centre.

Across the street, in the visitor entrance in B33 there is also a shop with lots of goodies you may want to check out.
