Open Day on 11 October 2025: a beautiful day! 🌞
400 visitors, 42 volunteers, 10 science workshops including one for children, 4 tour routes: Thank you so much for sharing this with us, wrote one of our visitors in a message. Thank you to her and the 399 other people who, like her, pushed open the doors of CEMES (including those of La Boule🔮, see photo): we’ll have to do it again!
