Fréjus contains a medieval city as well as a popular seaside resort. Created by the Romans, it attracts many tourists because of its history, cultural and artistic qualities, its well maintained beaches, the sea and sporting facilities. There are numerous places of interest in the area, all are reasonably accessible from Fréjus because of its convenient location. The history of city is very similar to that of Provence. It was destroyed many times in spite of the presence of the Roman Legions. In 49 B.C., Julius Caesar decided to have the Adrian Way built linking Italy with Spain. In those days the Phoenicians of Marseille had already set up a colony on the site, but it was the Roman emperor who gave the port its prosperity and the city its name of 'Forum Julii' meaning 'market of Julius;' he also named its port 'Claustra Maris' (The sea bolt). It went on to become one of the most important ports in the Mediterranean, until the Pax Romana, by denying Forum Julii its military activity, marked the beginning of its decline. The decay of Rome led to that of the cities of its empire. Between the 7th and the 9th centuries, Muslim invaders repeatedly raided the city. The sea encroached on the land while invasions by the Muslims and pirates left the monuments in ruin. By the 10th century there was very little left of the colony, mostly rubble. Sea-borne silt clogged up the port and led to the formation of a huge swampy plain, which then separated the village from the sea.
