Long Night of the Sciences

June 28, 2025

On the "smartest night of the year", numerous scientific institutions and laboratories open their doors and invite visitors to participate.

Once a year, numerous scientific institutions in Berlin and Potsdam invite visitors to laboratories, archives, libraries and lecture halls that are otherwise not open to the public. From 5 PM until midnight, visitors can participate in exciting experiments, learn about current research results and enjoy stimulating conversations. Around 27,000 visitors took advantage of this opportunity last year.

Where Scientists and Citizens Exchange Ideas

What makes the Long Night of the Sciences so special is the personal encounter between scientists and citizens, the thrilling experience of discovering usually "hidden" places, and the vivid atmosphere of a nightly event. Above all, it's not only the visitors who learn a lot this night - the scientists, too, get inspiration and useful feedback from their dialogue with the public. Therefore discussion groups and join-in activities have increased from year to year, including over 300 events for children and young people.
