Oppidum Uetliberg

Oppidum Uetliberg was a La Tene era Celtic fortification near the summit of Uetliberg hill in the canton of Zurich, Switzerland, dating to the 5th century BC (late Hallstatt/early La Tene period) [1]. One of the most important Iron Age fortifications in Switzerland, it featured walls up to 14m high and 35m wide enclosing a large settlement with two inner defensive rings [1]. The hilltop was settled from at least the Neolithic period, with the oldest artifacts dating to around 4000 BC among some 60,000 total finds [1]. Early excavations were conducted in the 1830s and 1860s [1].
