The Belgrade Fair or Beogradski Sajam (Serbian Cyrillic: Београдски Сајам) is a large complex of three large domes and a dozen of smaller halls which is the location of the major trade fairs of the capital city of Serbia. It is located in the municipality of Savski Venac, on the right bank of the Sava river. One of the most recognizable landmarks of Belgrade, it is colloquially referred to only as "Sajam".
Sajam is located on the Sava's right bank, in the western foothills of the Topčidersko Brdo and the neighborhood of Senjak, built on it. The Topčiderka river flows into the Sava, in the Bay of Čukarica, just south of the fair complex, while Novi Beograd and the peninsula of Mala Ciganlija are just across the Sava, which is at this point the narrowest (200 meters).
Originally, complex was built in 1938 in the modern neighborhood of Sajmište in Novi Beograd, across the Sava. As it was turned into the Sajmište concentration camp, it was not reconstructed after 1945 and a new Sajam was built on its present location in 1957. It was constructed by the architects Branko Žeželj and Milorad Pantović. Since then, Sajmište became known as Staro Sajmište ("old trade fair").
Area in the vicinity of the Sajam is among the busiest transportation sections of Belgrade. Entire complex is surrounded by the railways and both railway bridges over the Sava which connect old and new sections of Belgrade, are crossing the river at Sajam: old bridge, right on the northern tip, and new bridge which rises above the Sajam itself. "Boulevard of Vojvoda Mišić" which runs next to the complex is a major route which connects outer neighborhoods like Banovo Brdo, Čukarica, Žarkovo, Košutnjak and Topčider, and thus one of the busiest single streets in Belgrade, well known for daily traffic jams. Just north of the Sajam is a highway and one of the largest interchanges in Belgrade, Mostarska Petlja, and a Gazela bridge over the Sava. Additionally, the tram lines are passing through the boulevard too, and the very first tram line in Belgrade passed through this are (Gospodarska mehana) connecting Kalemegdan fortress and Senjak.
