ESSLLI 2021 will be held at the Utrecht Science Park in the Uithof, Utrecht.
The buildings that we will use are the Koningsberger, Buys Ballot, and Minnaert buildings. These are next to one another and connected. There is no need to go outside to go from one building to the other.

The Utrecht Botanic Gardens are opposite the Koningsberger building. All participants of ESSLLI2021 can enter the botanical gardens for free by showing their participant badge.
