There is only limited archaeological evidence from the city's foundational period as there were almost no traces left of the Celtic town, except for some burial sites with grave goods - the necropolises found at the locations in the modern neighborhoods of Karaburma and Rospi Ćuprija. These contained valuable artistic artefacts, that belong to the warriors of the Scordiscan tribe. A considerable Celtic cultural influences have been woven into the spiritual culture of the Singidunum inhabitants, and later mixed with Roman classical cultural elements.
