When digging for the future Rajićeva shopping mall began in 2004, remains of the antique and late antique layers were discovered, so as the remains of the southwest rampart route and double trench in the direction of Kralja Petra Street. The trench from the 3rd century was buried and full of coins, lamps, ceramics and jars. Next to this locality, at the corner of Knez Mihailova and Kralja Petra, an area paved with the cobblestone dating from the 2nd century was discovered. It was a public space, located right before the entrance into the fortress. During almost every construction in Knez Mihailova and the neighboring streets where digging is involved, remains are being discovered. In 2008 in Čika Ljubina Street remains of the house from the 4th century was discovered, which included the part of the floor and doorstep of the main entry door. Part of the walls was decorated with frescoes. Similar findings are discovered in Kosančićev Venac and Tadeuša Košćuškog. Remnants of the Roman castrum from the 2nd century were discovered beneath Tadeuša Košćuškog during the reconstruction in June 2009. They were conserved and reburied. In Cincar Jankova Street, five graves from the late 1st century were discovered so as the three canals. Archaeologists expected to find a southeastern route of the castrum ramparts, but due to the mass wasting in the area and the leveling of the terrain, the route was destroyed in time.
