Oppidum (plural oppida) was the name used by Caesar to describe the Celtic towns that he discovered during his conquest of Gaul. In archaeology, the term is now used to describe all fortified Celtic sites covering a minimum area of 15ha and dating back to the second half of the 2nd and 1st centuries BC (the late La Tène period). These towns were both economic and political centres.
Oppidum: The term used by Julius Caesar to describe fortified tribal centres encountered by him in Gaul in 58–51 bc which did not merit categorization as cities (urbes). In archaeological usage it is applied more generally to fortified sites and large permanent settlements of the late pre‐Roman Iron Age in Europe. These served as centres for administration, trade, craft production, and religion.
