The
Oppidum of Manching was a large
Celtic proto-urban or city-like settlement at modern-day
Manching, near
Ingolstadt, in
Bavaria,
Germany. The settlement was founded in the 3rd century BC and existed until c. 50-30 BC. It reached its largest extent during the late
La Tène period (late 2nd century BC), when it had a size of 380 hectares. At that time, 5,000 to 10,000 people lived within its 7.2 km walls. Thus, the Manching oppidum was one of the largest settlements north of the
Alps. The ancient name of the site is unknown, but it is assumed that it was the central site of the Celtic
Vindelici tribe.
