Dom Sindikata or Trade Union Hall (Serbian: Дом Синдиката) is a non-residential, multi-purpose building in downtown Belgrade, the capital of Serbia. Finished in 1957, by the 1970s it became the most popular entertainment venue in the city, nicknamed the Belgrade Olympia and later was adapted into the city's first multiplex. The building was declared a cultural monument in 2013.
Dom Sindikata is located on the Nikola Pašić Square, in the municipality of Stari Grad. The building marks the north and north-east border of the square. A wide passage through the building marks the entrance into the Bezistan, which is the shortest pedestrian connection with Terazije, the central city square. Terazije Theatre, McDonald's restaurant and Hotel Kasina are located in the buildings which lean on Dom Sindikata in the east. In front of the building, on the square, there is a large fountain and across the square are the Historical Museum of Serbia and the House of the National Assembly of Serbia. Western façade is located along the Dečanska street, and north of the building is an entrance into the Terazije Tunnel.
It was projected by Branko Petričić and the construction began in 1947. Since 1953, the Soviet construction workers were employed on the site. The building is finished by 1957. That year the first seminar was held and the first movie show was Only people by Branko Bauer. On 18 November 1957 the first musical show was held, too. The Great Hall with 1,600 seats, became one of the central entertainment multi-purpose venues in Belgrade (concerts, shows, cinema). Conductor Mladen Jagušt stated that the hall is one of the five in Europe with the best acoustics. In the 1970s and 1980s it became a prestigious scene, Belgrade's version of Paris Olympia.

King, Robert de Niro, Elizabeth Taylor, Richard Burton, but also the New York Philharmonic and Berlin Philharmonic.
