During almost every construction downtown where digging is involved, more remains are being discovered. In 2007, on the location of the former kafana "Tri lista duvana" at the corner of Bulevar Kralja Aleksandra and Kneza Miloša street, several necropolises were found. Just across, in Pioneers Park, there is Archaeological Site Pionirski Park. When the underground garage was dug, 19 tombs were 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 the streets of Kosančićev Venac and Tadeuša Košćuškog. Also in 2008 remains from the late Antiquity were found, while at the corner of Takovska and Kosovska streets. Roman tombs were discovered. 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 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. Remnants discovered in Kosančićev Venac are actually remains of the luxurious villa, with the floor mosaic and walls decorated in frescoes.
