What you see here is the entrance to the beating heart of this Vesalius project. We were able to convince the university to build the second-largest auditorium in all of Leuven on this land, which is used for the Faculty of Law and Psychology. A nice anecdote about this project is that we tried to make it the largest auditorium in Leuven. Pieter De Somer is that. We did everything we could to get more seats into the building than Pieter De Somer. Unfortunately, it did not work out and it became the second largest because of fire safety regulations. The complex part of this project was creating the large spans. There could not be a single column in this underground space, because you needed a wide auditorium with perfect sightlines. I remember writing my childrenβs names somewhere here in the concrete. I will not find it again.
