Royal Palace

This operated from July 1941 to October 1944 under Gestapo leadership; at least 3849 perished here. It's now a museum.

This is in 3 buildings. Old Museum is a general display of the history and culture of the former Yugoslavia. 25 May Museum is an oh-so-Sixties building named for the official birthdate of Josip Broz Tito (1892-1980). It displays presents given to him during his 27-year presidency: he amassed quite a collection of youth relay batons. House of Flowers is his mausoleum.

Orthodox monastery church built in 1935 in the Serbian-Byzantine style.

West African contemporary art.

The largest church in Serbia and one of the largest Orthodox churches in the world, under construction since 1935 and still not entirely finished. It's described as a temple (Hram) to distinguish it from the smaller St Sava Church (Tsrkva) adjacent. The crypt (downstairs from the main entrance) is an extensive, bright and polished area with walls covered with modern iconography, so it looks more like a metro interchange for Orthodox saints than a religious building. Services are held regularly here and in the Church, which you can also visit.

Built on its present site from 1600, the monastery's main structure is the Church of Archangel Michael. The other churches are modern.
