built a large complex of oil tanks during the Interbellum in the northernmost section of Čukarica, Careva Ćuprija. The zone was heavily bombed during the Allied bombing of Yugoslavia in World War II. Especially heavy was the bombing on 3 July 1944. The tanks, and the wider area of old and north parts of Čukarica were carpet bombed, resulting in almost complete destruction of the old core of Čukarica. Rebuilt after the war, the tanks in time became known as the Jugopetrol tanks. As a result of bombing, numerous unexploded bombs remained buried in the ground, and are occasionally discovered during the modern construction works, like Ada Mall in 2018, or residential complex in Banovo Brdo in 2021, which required evacuation of couple of thousands of residents for safe extraction of the projectile. Location Čukarica is completely surrounded by other municipalities of Belgrade: it is bordered by the Sava river to the west, municipalities of Savski Venac to the north and northeast, Rakovica to the east, Voždovac to the southeast, Barajevo to the south and Obrenovac to the southwest. Municipality is located southwest from the downtown Belgrade. It comprises the vast marshy woods of Makiš, on the eastern bank of the Sava river and the largest river island in Belgrade, Ada Ciganlija. At the suburb of Sremčica, Beogradski merokras, the most northern terrain made of limestone (karst) is located. Several of the most important roads in western Serbia start here: Lazarevac Road, Ibar Highway, Sava Highway, New Obrenovac Road, Old Obrenovac Road, etc. Also, the largest and most important freight train station and marshalling yard in the area (Belgrade marshalling yard) and the main installations of the Belgrade waterworks, including the water factory, are located in the municipality (Makiš). Čukarica was the first part of Belgrade that developed industry, in the late 19th and early 20th century and still is one of the most industrialized parts of Belgrade (Železnik, Žarkovo, Bele Vode), with commercial sections of the municipalities booming in the last 20 years (Banovo Brdo). Officially the longest street in Belgrade, Obrenovački put (Obrenovac road) is located in the municipality. According to Belgrade's Directory of Roads, it is 11 kilometers long. However, as the road passes through the forests and mainly uninhabited areas and stretches outside the urban Belgrade City proper (uža teritorija grada), most Belgraders consider the 7.5-kilometer-long Bulevar kralja Aleksandra to be the longest street.
