Officers Club building in Niš is located in the July 7th Park on the Nišava promenade. This building, built ten years after the liberation of Niš from the Turks in 1890, is under state protection and has the status of a cultural asset of great importance. During its existence, it was the place of the most important political and parliamentary events in Serbia.   

Of the many decisions made here, the most significant is the one during the First World War, when war sessions of the Serbian Parliament were held there and the Niš Declaration was made official, with the basic goal of uniting the Balkan peoples in the struggle for liberation and creation of a common state of Serbs, Croats and Slovenes.
