Terazije (Teh-RAHZ-ee-yeh) Theatre (read more here) is a very popular theater, showing fabulous musicals, for the most part. You can't see its entrance here, but on this large square is the back of the theater, which I'd never really paid attention to before. But look! Up out of the flat stones of the square rises this elevator that loads and unloads heavy props. I was fascinated to see it rise, since I never even knew it existed.
