During the time of the Romans, it was called gaul, but after the fall of the Roman empire the people were called franks which morphed into france. :)

The Pont du Gard aqueduct was built during the first century AD, specifically between 40 and 60 AD. It was constructed as part of a larger water supply system to bring water to the city of Nîmes in what is now modern-day France.

The Pont Du Gard is made entirely from stone (brick).

The Pont du Gard is a bridge which still stands and was part of the aqueduct which supplied water to the city of Nemausus (Nimes) in southern France. It is the greatest example of a Roman multi-pier bridge. The Romans built two or three tiers of arches on top of each other when they needed a bridge to reach a great height.

The Pont du Gard has three tiers of recessed arches with the main piers in line one above the other. The first two tiers have very high and wide arches and a third tier has low and narrow arches. It was built to carry an aqueduct to Nimes in southern France. It reaches a height of 48.8 metres (160 feet). The lower tier is 142 metres (466 feet) long and has six aches with a height of 22 metres (72 ft.). The second tier is 242 metres (794 ft.) long and has eleven arches 20 metres (66 ft.) high. The upper tier is 275 metre (902 ft.) long. It originally had 47 arches (only 35 have survived) 7 metres (23 ft.) high. The width of the first pier is 6 metres (20th.), that of the second pier is 4 metres (13 ft.) and that of the third pier is 3 metres (23 ft.).

He did not conquer Greece. He attempted to bring the independent Greek city-states under control to bring peace and stop them disrupting his empire, but failed. The Greeks went back to fighting each other.
