Festival

We are Science Week 2026

Date: Tuesday 19 May 2026 - Thursday 21 May 2026
Location: Gorlaeus Building
Einsteinweg 55
2333 CC Leiden

The most fun event of the year is coming up again: the We Are Science Week! For three days (19–21 May), the Gorlaeus Building will be the stage for all sorts of exciting activities. Compete with your team for victory in the Beat the Professor Pub Quiz, grab a free coffee from a real barista, or come and dance at our silent disco!

This year, you can relax on the campus square for three days and play games such as table tennis and table football. New this year is our clothes swap: tired of that one blouse, but still perfectly good for another round? Trade it in for an item of clothing of your choice. Nicely sustainable! And have you always wanted that Leiden Science hoodie or water bottle? Grab yours at the merchandise sale on Tuesday and Thursday! If the weather doesn’t cooperate, we’ll move the programme indoors.

Fancy a post-work drink at De Fusie? Lovely! The courtyard will be open as well.

The full programme will be announced soon. See you then!
