What do the finds at the Heuneburg hillfort tell us of Celtic society?

The Heuneburg hillfort is dated to the La Tene period of Celtic culture and is a treasure trove of archaeological remains: masonry and brickwork, evidence of trade with the Mediterranean world, jewellery-making, burial mounds, evidence of warfare, metalwork and various types of buildings. But recent finds also give evidence of disease and trade/travel to more distant parts of the world. this source-based task is designed for students of the NSW ancient History Syllabus for the Australian Curriculum.
