When Leiden was awarded the title of European City of Science for the year 2022, one thing was certain: following the European tradition of Youth Capitals and Cultural capitals, Leiden wanted to be the first European city to present a year-round science program for anyone with a curious mind. The aim was to connect science with society. That's easier said than done — yet still, it worked: throughout the city, from its smallest corners to the surroundings, special encounters took place between citizens and scientists.
