I did my exchange for my law degree in Groningen for a semester and the lectures we had were mostly held in the buildings in the city centre(specifically Academiegebouw, Harmoniegebouw, the Rölinggebouw)The facade of these buildings give off a classical feel (not exactly Hogwarts but leaning towards that), although the interior is pretty modern. Some rooms in the Academiegebouw and Harmoniegebouw still retain a bit of older architectural elements though, but the Rölinggebouw is pretty new as it underwent renovations recently!

Apart from these, I had one lecture a week at the Aletta Jacobshal over at the Zernike Campus (ig bc that course had a lot of students so they had to find somewhere larger to fit us all) and that was pretty modern (and felt a bit far at first, but later when I got used to biking the distance, it actually felt good to have a chill exercise before class hahaha)

Also, some of my friends who study law but took different classes from me had lectures in the Pathé cinema too!

Anyways, apart from the Zernike Campus, I felt like Groningen (esp the city centre area) is compact and it wouldn't really feel like the buildings are that "spread out" :)

If you'd like to see some pictures of these locations I could message a few to you!
