Plavi Horizonti is located in the western section of Zemun, stretching along the Belgrade-Novi Sad railway. It borders the neighborhoods of Altina in the north and stretches into the direction of Vojni Put II and Kolonija Zmaj on the southeast and Zemun Polje on the northwest.
Until the late 1990s the area was an uninhabited baren meadow. With the outbreak of the Yugoslav Wars in 1991, and especially after the 1995 Oluja action which forced out 250,000 Serbs from Croatia into Serbia, many refugees settled in this area, which resulted in creation of several new settlements (Altina, Plavi Horizonti, Grmovac, Busije). Plavi Horizonti and Altina grew into the small town, adjoining the Zemun's western urban area. The municipality of Zemun gives and estimate of 20,000 inhabitants for combined population of Altina and Plavi Horizonti.
As a non-planned settlement, Plavi Horizonti almost grew into a slum, quite contrary to its romantic name ("blue horizons"). After 2000, certain urbanistic arrangement of the settlement began: the roads and streets were paved, etc but many problems concerning the communal infrastructure remain.
