A: Paris, Île-de-France, France
About 250 BCE a Celtic iron age tribe called the Parisii established a fishing village near the river Seine (present day France)
Traditionally the original settlement known as Lutetia was thought to have been located on the Île de la Cité; however it is now believed that the largest pre-Roman settlement in what is now Paris may have been in the present-day suberb of Nanterre.
