City walk in Belgrade city center takes visitors around historical places related to Luka Ćelovic, one of the most successful entrepreneurs in Serbia, who donated all his assets to University of Belgrade. His generous contribution significantly added to the University of Belgrade becoming one of the richest institutions of higher education in Europe at that time (1928). Walk ends at the point that could be taken as the final stage of an era in Serbian and Yugoslavian culture ‒ home of distinguished writer, diplomat and scholar Vojislav Jovanović Marambo who donated his house and exquisite book collection to the University Library.
