Frejus is the oldest Roman city in Gaul, founded and named after Julius Caesar in 49 BC. It was once the most important port after Marseille, and was on the Aurelian Way, the great Roman road between Italy and Spain. Some of the walls and remains of the gates of the Roman city can still be seen, including the Lantern d’Auguste, the tower which once guarded the old port. The Porte de Rome stands at the end of the original aqueduct that supplied the city with water, and you can still see traces of the channels and arches on its 40km journey through the countryside. There are also fragments of a 1st century theatre, where performances are still held. Best of all is the Arena, which once accommodated 6000 spectators and continues to be used today for bullfights and musical events.
