The Roman settlement on Gamzigrad prior to the imperial palace Felix Romuliana

Archaeological research at Gamzigrad-Romuliana has uncovered evidence of a significant Roman settlement predating the construction of Emperor Galerius' imperial palace, Felix Romuliana. Traces of earlier buildings, dating from the late 2nd to the end of the 3rd century AD, were found within the fortified residence, including a three-aisled structure south of the 'Large Temple,' a building beneath the early southern tower of the East Gate, a substantial edifice under the Galerius Baths, and another building in front of the later southern tower of the West Gate. This settlement likely functioned as a mining, metallurgical, and commercial hub (vici or civitas) in the Timok Valley during the 3rd century, providing new insights into the region's economic and social development before the imperial era.
