FRANCE: Roman Ruins in Provence - Nimes and Arles

The Roman arena in Nimes, built around 100AD, is not one of the largest amphitheatres that the Roman's built, but, is the best preserved of them all.

Amongst the 400 Roman amphitheatres that are still in existence, this among the 20 largest. 

The Roman’s specifically designed their amphitheatres for putting on spectacular combats between gladiators or animals.
