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.
