It was decided to build the fairgrounds complex adjoining to the already existing settlement. The foundation stone was ceremonially placed on 6 June 1937. It was built in three months and the facility was open on 11 September 1937. It was the site of the new Belgrade fair (hence the name) with modern and artistic buildings and constructions, including high metal spike construction, which became known as the Central Tower. Designed by the architects Milivoje Tričković, Rajko Tatić and Đorđe Lukić, it was envisioned as the monumental modern complex, with the Central Tower as the domineering motif. Around it, pavilions for the exhibitions were built: five Yugoslav, one for the “Nikola Spasić Foundation” and national pavilions of Italy, Czechoslovakia, Romania, Hungary and the Dutch company Philips. The complex included: of roofed exhibition space, of open exhibition space, of lawns and flower beds and of roads and paths.
