In 2004 digging for the future shopping mall in Rajićeva Street began, next to the Knez Mihailova. 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. 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 right before the entrance into the fortress.
