On the 22nd of December 2022 the Stadsgehoorzaal will be transformed into the Finale Festival of Leiden European City of Science. You're invited to celebrate this event with us!

The Finale Festival will take place from 16:00 (4pm) until 22:22 (10:22 pm). We'll look back on an incredible year filled with science, knowledge, art, and craftsmanship. Of course, you'll also be able to re-experience some wonderful activities. But we'll also look towards the future. After all, the daily topic on the 22nd of December is: FUTURE. 

Are you curious? Then this Finale Festival is meant for you! Everyone is welcome and you can attend free of charge! Take someone with you or tell others about this event. We'd love to see you on the 22nd of December!  

Do keep in mind that this event will mainly be in Dutch. Visitors that do not speak Dutch are also welcome. We will accommodate for English-speaking visitors wherever possible.

Get your free ticket here! 


The festival terrain is opened from 16:00 (4pm) to 21:22 (9pm). This means you'll be able to visit the festival at your own leisure between those times. Do you want to get inspired right before dinner? Or get away from the evening cold and partake in a fun activity? You can! Everything is possible!
It will take about 90 minutes if you want to do all of the activities.
