Drobeta

During the reign of Emperor Hadrian (117–138 AD), the settlement was declared a city in 121 AD. At this point the population had reached 14,000. During the reign of Septimius Severus (193–211 AD), the city was raised to the rank of a colony (193 AD), which gave its residents equal rights with citizens of Rome. As a colony, Drobeta was a thriving city with temples, a basilica, a theater, a forum, a port and guilds of craftsmen. In the middle of the 3rd century, Drobeta covered an area of 60 hectars and had a population of almost 40,000 inhabitants.  (From Wikipedia)
