Nesactium

The heavily fortified capital of the Histri, Nesactium sits nourished by a river and would not fall until the Romans diverted it in 177 BCE to help with their siege and finish the conquest of Istria. This was not enough to make Nesactium surrender, and Livy reports that the local garrison massacred the Histrian women and children atop the walls in an effort to scare off the Romans, but the Romans were not deterred, scaled the walls, and slew most of the Histrians and captured 5,632 people as slaves. Nesactium was resettled for a time, but would never regain its prominence and eventually be abandoned.
