Today, Lyon is the third-largest city in France but during ancient times, it was the largest. At the time, the capital of the Gauls was called Lugdunum. Between the end of the first century BC and the second century AD, all the monuments worthy of a Roman capital would be built in the city and Lyon would become a showcase for Rome in these lands conquered by Julius Caesar.

With its 2,185 monuments, today, Paris is the world's most touristic capital city! But in the 1st century BCE, the home of the Gallic Parisii tribe was conquered by Romans and was gradually rebuilt into the Roman city of Lutetia. Ruins including a forum, amphitheater, and Roman baths still remain.
