University Library , Boulevar revolucjie.
Muzej revolucije , trg Nikole Pasica 11 (open 10-17). The Museum, whose full name is Museum of the Revolution of the Nations and Nationalities of Yugoslavia is at present closed to visitors. In 1997 there was, at the ground floor, an exhibition (+-) on the Jasenovac concentration camp in which the Croat ustasa killed, between 1941 and 1945, a few hundred thousand Serb, gypsies and Jews. Interesting to understand why the hate is not over, but to be recommended only to the hardened hearts. Other museums celebrating the former regime include Tito's last residence and tomb on the Topcider hill, but I have not been able to check the opening times.
