University of Warsaw Library.
Post-modernism with elements of brutalism and...pre-solarpunk I guess?
(the latter is more visible on the outside - more pictures in the wikipedia article)
@wistahe yeah, it does feel very "inside is outside", especially that if you leave through the main entrance (between these columns in the middle of the photo) you end up in a paved sidewalk between the library half of the building and a second, commercial half of the building, but still under that same steel-glass roof!
Also, holy shit, gmaps has a streetview from the inside!
