In 1990 CERN has opened the Microcosm permanent exhibition to explain to the general public CERN's research and to communicate the excitement of science. During the 1997 summer, Microcosm has been given a complete facelift, updating the contents, introducing more interactive displays and adding many new exhibits. The new exhibition has opened on 1 September 1997. It explains the basic principles of high energy physics in a way which is easy to understand and enjoyable to all.
Entrance is free.
