Košutnjak gained a sort of historical notoriety as prince of Serbia, Mihailo Obrenović III and his cousin Anka Konstantinović were assassinated while walking in the park on 10 June [O.S. 29 May] 1868, and when Ivan Stambolić, Slobodan Milošević's political opponent was abducted from the park on 25 August 2000 and later assassinated and buried at Fruška Gora. There are also remnants of the German cemetery and the monuments to the Serbian soldiers erected by their adversaries, German soldiers, in World War I.
