An Early Iron Age fortified site and hillfort of the Hallstatt period on the upper Danube in Baden-Württemberg, Germany. The site was the center of the dominant Celtic chiefdom in southwest Germany c 600-500 BC. Wine amphorae and Attic Black-Figure pottery were imported from the Greek city of Massalia, demonstrating Heuneburg's wealth. There are nearby princely burials of the same date, including the rich Hohmichele tumulus. This covered a timber mortuary house containing the body of an archer accompanied by a wooden wagon and precious offerings. The site has five main building phases, the most remarkable of which was the second, when the traditional timber-framed construction was replaced by a Greek type of construction, with a bastioned wall built of mud-brick on stone foundations.
