Parisii
Île de la Cité, Paris, FranceBetween 250 and 225 BCE, during the Iron Age, the Parisii, a sub-tribe of the Celtic Senones, settled on the banks of the Seine. At the beginning of the 2nd century BCE, they built an oppidum, a walled fort, whose location is disputed. It may have been on the Île de la Cité, where bridges of an important trading route crossed the Seine.
