The oldest traces of human occupation in Paris, discovered near rue Henri-Farman in 2006, are from encampment of hunter-gatherers dating from between 9800 and 7500 BC.[1] Between 250 and 225 BC, the Parisii, a sub-tribe of the Celtic Senones, settled on the Île de la Cité and on the banks of the Seine, built bridges and a fort, minted coins, and began to trade with other river settlements in Europe.[2]
