Belgrade's elegant Orthodox church, StÿMark's, was built in the 1930s, replacing its predecessor dating from 1835. Exhibiting the Serbo-Byzantine style, its architecture is inspired by the famous Gra?anica Monastery. In the southern part of the church you can admire a sarcophagus with the relics of Emperor Du?an. It also houses one of the largest and richest collections of icons from the 18C and 19C.
