 When the neighboring island of Ada Huja was connected to the mainland thus becoming a peninsula, Karaburma's area on the right bank of Danube also became known as Ada Huja, so Karaburma is now few hundred meters away from the river.The oldest settlement known by name on the territory of modern Belgrade was found in the Karaburma area.Remains of the Celtic (and later Roman) settlement of Singidunum were found near Karaburma and neighboring Rospi Ćuprija, including necropolis (Horseman's grave 16) rich in artifacts and parts of "dunum", fortress, so it is believed that the settlement itself was located here.
