There sure are a lot of famous Leidenaren!


In the four and a half centuries of its existence, Leiden University has graced the world with many great scientists! Unfortunately, only in the last century has that list become more diverse. As this treasure hunt dives into Leiden’s past, the individuals celebrated here are all male and white… But the importance of their scientific discoveries and their connection to the city of Leiden must not be forgotten.

Ready to learn more about them?


Leiden Ludens has set up a treasure hunt through town, passing famous and less famous locations related to world-renowned Leiden University alumni.
Along the way, you will be solving riddles and puzzles to the best of your code-cracking abilities! You can use this handy pdf to keep track of your answers and solve the final riddle.


Anyone can participate in this treasure hunt! The locations are all easily accessible and no entry fees for cultural locations are required for participation (though two locations are not accessible at night).


The trail of legends will be open during all of 2022, so take your time to finish it. You can finish it all in one go, or leave it and pick it up again later, it’s completely up to you!


The start of the trail will be around the Volkenkunde Museum! Find the sticker with our red and white QR code to receive your first puzzle.
But you need not start here if you don’t want to. It’s a circular trail, and you may jump in at any point!


No tickets will be required for this event, as you’ll be following a laid out trail through all of Leiden at your own leisure.
Start whenever you like, and take all the time you need to solve the mystery!
