Located in the heat of the city, Nikola Tesla Street to be exact, this famous gallery was opened in 1968 by renowned Croatian contemporary artists such as Edo Murtić, Frano Imunović, Zlatko Prica, Kosta Angeli Radovani and others. These days, exhibitions from artists that come all over fill the calendar at Forum as well as round tables and discussions which stem interest. 
Info: Belongs to KIC - Cultural Information Center behind the corner, a nice place for coffee, movie, or an exhibit.
