The original earthen and wooden fort stretched around the Studentski Trg and Knez Mihailova Street. The oldest Roman graves were discovered in this section, dated to the 1st and early 2nd century. In the Lower Town section of today's Fortress, remains from the 2nd and 3rd centuries were discovered. They include thermae, residential objects and a shrine dedicated to Mithras. The forum, which included the temples of Jupiter and Nemesis, was located close to the Cathedral Church, where the modern building of the National Bank of Serbia in the Kralja Petra Street is situated. Another thermae were located in the Čika Ljubina Street. The entire settlement was surrounded by vast necropolises, while the main and the largest one stretched along the Via Militaris in the direction of Viminacium, today's Bulevar Kralja Aleksandra where numerous graves, grave steles and sacrificial altars were discovered.
