Archaeologists have mapped a previously unknown Roman city near the Danube in Austria—and its size is surprising.
The settlement at Stein covered approximately 25–30 hectares and had a regular Roman street grid plus an amphitheater estimated to hold around 8,000 spectators.
Beside it stood an auxiliary Roman fort housing roughly 500 soldiers.
Researchers are now trying to understand why such a large urban center developed around this relatively small military garrison. They are also investigating whether the site could be the lost Roman settlement of Claudivium mentioned by Ptolemy, although that identification remains unconfirmed.
This discovery offers a remarkable glimpse into how Roman soldiers and civilian communities lived together on the empire's northern frontier.
