 The oldest settlement known by name on the territory of modern Belgrade was found near the Rospi Ćuprija.Remains of the Celtic (and later Roman) settlement of Singidunum were found near Rospi Ćuprija and neighboring Karaburma, including necropolis rich in artefacts and parts of "dunum", fortress.These remains represent a limited archaeological evidence as there were almost no traces left of the Celtic town, except for them.
