During World War II it was renamed "Serbian Ada" (Srpska ada). The first part of Ada Ciganlija's name, ada, means "river island" in Serbian, a word of Turkish origin (meaning "island"), but in landlocked Serbia it specifically denotes river islands, beside the already existing Serbian word for island, ostrvo. A river island can also be referred to as ostrvo (e.g. Veliko Ratno Ostrvo) but never vice versa. Human history Antiquity The remains belonging to the Scordisci, a Celtic tribe which founded Singidunum and Taurunum, the predecessors of Belgrade and Zemun, respectively, were found. 1680s–1914 Area of Ostružnica, near the southern tip of Ada Ciganlija, was a location of the Long Bridge, the first permanent bridge in Belgrade's history. As the opposing, Syrmian side across the Sava was a vast marsh at the time (modern New Belgrade), the bridge didn't stop at the bank but continued for some length above the swamp. Because of that, the people also called it the Bridge above the marsh (Most preko močvare). The bridge was built by the Austrians to help them conquer Belgrade from the Ottomans during the 1688 Siege of Belgrade. According to the records, a seasoned Belgrade master craftsman Đorđević "in only one month, with the help of his 400 workers, built the Long Bridge, using 2,000 tree trunks, 1,100 wooden piles, 15,500 bundles of palings and 12,000 palisade pickets." Right next to it, bit closer to Ada Ciganlija, the Austrians constructed another, classical pontoon bridge, which "leaned on the Long Bridge". The Romani settlement which existed on Ada in the 17th century was displaced from the island to the Sava's right bank, at the mouth of the Topčiderka, before the Austrian occupation of Belgrade from 1717 to 1739. It is not known whether it happened some time before or during the fighting from 1716 to 1718. One map from the Austrian period shows a Romani settlement with 24 houses at the mouth of Topčiderka. Maps also show that the settlement existed during the next Austrian occupation from 1788 to 1791. When the Austrian army attacked Belgrade in the 18th century, the Ottomans expelled Serbian population from the city, so they temporarily settled on Ada. When Belgrade was liberated by the Serbian rebels in the First Serbian Uprising, leader of the uprising, Karađorđe, granted the island to Mladen Milovanović, the first city chief. After the collapse of the uprising, Milovanović fled to
