It's in both actually (from GPT): CERN, the European Organization for Nuclear Research, is indeed situated on the border between Switzerland and France. The main site, hosting the Large Hadron Collider (LHC) and other significant experiments, straddles the two countries. Most of the main facilities, including the main administrative buildings and the majority of the research laboratories, are located on the Swiss side near Geneva.
