The Globe of Science and Innovation is an emblem for CERN and a symbol of sustainable development for all. It is 27 metres high and 40 metres in diameter, which is about the size of the dome of Saint Peter's in Rome! A unique visual landmark by day and by night, the Globe of Science and Innovation is a symbol of Planet Earth. On the ground floor of the Globe, the « Universe of Particles » exhibition takes the visitor on a journey deep into the world of particles and back to the Big Bang.
