White Hill

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

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.

Nikola Tesla (Никола Тесла, 1856-1943) made huge contributions to electric engineering, pioneering alternating current (enabling long-distance high-energy transfer), radio (underpinning today's mobile comms) and AC motors as used in household and office machinery. Half of this small museum is dedicated to Tesla's personal effects, while the other half contains models of his inventions. English-speaking tours start at the full hour and include demonstrations. Long lines build up at peak hours.

Residence of the royal family of Serbia. You can only visit on a guided tour (in English or Serbian), booked through the Tourist Information Offices. The tour takes in the White Palace, with a large art collection.
