Input: Consider Input: Question: Who governed Noricum after the Romans turned it into a province? Passage:Archaeological findings in the area date back to the Neolithic era, especially the stilt houses of the Mondsee group culture, who settled the region from about 3800 BC onwards. The Germanic name hall of several settlements refers to the region's numerous salt mines, which had been in use at least since the days of the Celtic Hallstatt culture, centered at the mining town of Hallstatt. These operations were continued by the Romans, after the area had been incorporated into the Noricum province in 15 BC. A Roman settlement and salt evaporation pond at Hallstatt is documented about 100, affected by several Germanic invasions after the Marcomannic Wars, until the province was finally evacuated at the behest of the Italian king Odoacer in 488.
