Back on a journey of discovery
The Leiden Discoveries route, a tribute to the many discoveries and scientific breakthroughs made in Leiden, will be fully accessible again from spring 2025!
In celebration of the university’s 450th anniversary, the signs along the route will be refreshed, and thanks to a redesigned website, visitors will soon be able to embark on their journey of exploration through Leiden’s scientific history with even greater ease.
The route, an initiative of emeritus professor Ton van Raan, was established in 2015 in honour of the university's 440th anniversary by the Leiden Discoveries Foundation, with support from the Municipality of Leiden and Leiden University.
