Leiden 2022: European City of Science

unlock_Leiden in 2022 as the European City of Science!

In 2022, Leiden will be the first European city to present a 365-day science festival. Perfect for anyone with a curious mind, the festival will explore science, knowledge, art, and skills through various scheduled exhibitions, workshops, excursions, activities, and events. The major issues of our time will be discussed during international conferences and scientific meetings. But that’s not all; Leiden European City of Science 2022 will also offer an intriguing program in which a different topic is explored every day. This will invite local residents to interact directly with science. From conferences to neighbourhood initiatives: Leiden European City of Science 2022 shares some of the most important and interesting current topics of knowledge with the heart of society.

365-day Science Festival

On January 1, it’s all about the EURO, and on April 4, it’s about PLACEBO. In 2022, each day will have its own theme. The annual four-part program covers the entire knowledge spectrum: from fundamental science to citizen science. The Year of Events consists of hundreds of public activities throughout Leiden based on science, knowledge, art, and skills. Included in this is the 10th edition of the largest interdisciplinary science conference in Europe, EuroScience Open Forum (ESOF), which will take place from July 13 to 16. In September, young, talented researchers from all over the world will come to Leiden for the 33rd final of the EU Contest for Young Scientists (EUCYS). And that’s not all. Through the co-creation project, Knowledge Through the Neighbourhoods (Kennis door de Wijken), activities based around one of 365 interesting, accessible topics will be organised every day in one of the 101 neighbourhoods of Leiden, Zoeterwoude, Voorschoten, Oegstgeest, and Leiderdorp.


Upcoming Events


In 2022, Leiden will host the ESOF conference. The EuroScience Open Forum is the largest multidisciplinary scientific conference in Europe. Working in close collaboration with EuroScience in Strasbourg, the tenth edition will take place between July 13 and 16, 2022, in Leiden.



The year 2022 has been declared the European Year of Youth by the European Commission. That’s why it’s extra great that Leiden2022 has also succeeded in bringing the 33rd edition of the EU Contest for Young Scientists (EUCYS) to Leiden. In this way, we can boost the desire of younger generations to get involved in European City of Science 2022. The competition for talented young scientists, up to the age of 24, will be held from 12-18 September.

Convention City

In 2022, Leiden will be the hub of international science. For a whole year, the knowledge region’s calendar will be packed with conventions, conferences, symposia, and workshops, where science is used to tackle the big questions of our time.


Life Sciences & Health Week

More than 400 years have passed since the first medicinal plants were brought to the Hortus Botanicus, and now, Leiden boasts its own Bio Science Park. The past four centuries of medical innovation have seen one discovery lead to the next. They were years in which greats such as Albinus, Boerhaave, Von Siebold, and Einthoven flourished and now, 30,000 bright minds are working every day on the breakthroughs of tomorrow. Herman the genetically-engineered bull, Factor V, the Janssen Vaccine, and regenerative medicine are the impressive results of such research.
