With a total area of 1,662 hectares, the Heidengraben is not only the largest Celtic oppidum in Germany, but also one of the largest in Europe. The term "oppidum" for city-like, fortified large settlements of the late Celts of the second and first centuries BC in Central Europe was adopted based on Caesar's description of such complexes of the Celts in Gaul.
