About European City of Science

The European City of Science hosts the Science in the City Festival which is an important feature of every EuroScience Open Forum dedicated to people of all ages who are curious about science and technology. It is one of the largest public engagement in science and technology events in Europe.

The Festival hosts international performers and is multilingual, engaging tens of thousands of participants coming from all over the world.


Leiden has been awarded the title European City of Science for the year 2022. A prestigious title which also grants the right to host ESOF2022, the tenth edition of the biggest biennial multidisciplinary science convention of Europe.

Many cities claim to be cities of science. Leiden truly is it. In Leiden talent and expertise have been bringing about innovations for many centuries. In that spirit, all city partners came together towards the common goal of securing the title of European City of Science. For Leiden city it is the logical next step on the international field.

For the first time, the Science in the City in the City Festival will offer a year-round programme with an international character, following the example of the European Capitals of Culture. In 2022, Leiden will present a 365-day programme full of activities, lectures, workshops, excursions, exhibitions and events for anyone with an inquisitive mind. For scientific professionals, Leiden will be the ultimate European stage for the Dutch knowledge field in 2022.

With the motto ‘a little wiser every day’, every day, one of the 101 neighbourhoods in Leiden and its surrounding region will be visited. And every day will revolve around a different topic. From peas to privacy and from bees to beer, there will be something for everyone.

Henri Lenferink, Mayor of Leiden stated: “In 2022, Leiden will be the stage for the top of European sciences. During European City of Science 2022 we have the ambition to inspire as many curious people as possible. One way of doing so is with the unique 365-day programme ‘Knowledge through the Neighbourhoods’. Preparations are in full swing, and we look forward to a fantastic knowledge and science year in Leiden.”

The Leiden European City of Science 2022 programme consists of three separate lines: Contemplate, Participate and Celebrate. The ESOF conference will be held as one of the Highlights taking place from the 13th to 16th July 2022 in the Contemplate programme.
