Ever wondered what the great big metal ball on Bogovićeva street is? It’s, of course The Sun - a sculpture made by Ivan Kožarić in 1971. In 2004, Davor Preis created a scale model of the solar system around this mighty sun at the following locations throughout the city: Mercury (Margaretska 3), Venus (Trg bana Josipa Jelačića 3), Earth (Varšavska 9), Mars (Tkalčićeva 21), Jupiter (Voćarska 71), Saturn (Račićeva 1), Uranus (Siget 9), Neptune (Kozari put), Pluto (Aleja Bologne - underpass). Preis never revealed the locations of the planets, so finding them turned into a game lasting until the last planet was “discovered” in 2006.
