Like this place to visit as it is very quiet University.
Really nice and interesting with the scholar statues.
It is small and very calm. I'd like you to go inside. You can take a break.
Very serious and quiet University yard behind the main entrance, not big. Alongside the corridor you can find statues of remarkable scholars in the history of university Vienna. Library is a must go too.
If you walk by the university, DO go inside! The entrance hall and inner court yard are beautiful and full of monuments celebrating the university's presitigious professors such as Freud. Vienna is maybe the most beautiful city I've seen, but this visit to the university was for some reason the favourite thing I did.
