Magnificent Roman Poetovio
People first settled at the lively crossroads of merchant roads, where it was safe to cross the Drava River, already at the end of the 3rd millennium BC. The area was settled by the Celts in late Iron Age, but the city really started flourishing with the arrival of Romans. Archaeologists believe that some 30 thousand people lived in the greater area around Poetovio, which was one of the most important Roman army base camps, at the time.
In the middle of the 5th century the territory was plundered by the Huns, and later gradually occupied by the Slavs. At the end of the 8th century Ptuj became part of the Frankish Empire, and at the end of the 9th century the city came under the power of the Salzburg Archbishopric.
