The Cité des Sciences invites you to envision its future during a special weekend.

Created in 1986, the Cité des Sciences marks its 40th year of existence in 2026. Rather than going through a midlife crisis, the Cité invites the general public to help imagine and rethink the future of this cultural and scientific venue in Paris.
