Leiden Discoveries

In 2025, Leiden University will celebrate its 450th anniversary. The theme of this anniversary is 'Ahead of Its Time'. Through Leiden Discoveries, we showcase how researchers in Leiden were often far ahead of their time with their groundbreaking discoveries. We invite you to explore the route and discover the fascinating stories behind them.

About Us

Leiden Discoveries was originally an initiative launched in 2015 by Leiden University, Leiden, City of Discoveries, LURIS, and the Leiden Bio Science Park, with support from the Prins Bernhard Cultuurfonds and VSB Fonds. In 2025, the website was updated by Leiden University, Leiden & Partners, and the City of Leiden.
