Sometimes architects will take two tall (say 8-10 storey) buildings that happen to be near each other, and build a glass roof between them.
Down on ground, the area which originally would have been a street, or alleyway or something, now becomes a quasi-outdoor, courtyard type space where people can hang out and look up a roof/ceiling many storeys in the air.

I keep thinking "atrium" or something like that.
