Bassianae

Bassianae was the second-largest Roman town in Syrmia after Sirmium, located near modern Donji Petrovci in Serbia's Vojvodina province. Founded as an autonomous civitas in the 1st century AD, it gained municipium status in 124 AD and was recorded as a colony by 214 AD. Situated on the road connecting Sirmium and Singidunum, the town was successively part of Pannonia, Pannonia Inferior, and Pannonia Secunda. Archaeological excavations since 1882 have uncovered walls, towers, ceramics, coins, sculptures, and mosaics, while 2014 surveys using ground-penetrating radar and magnetometry mapped buried structures across the intramural area.
