The present site of Cassis was first occupied between 600 and 500 BC by the
Ligures, who constructed a fortified dwelling at the top of the Baou Redon. These people lived by fishing, hunting, and farming. The current site of Cassis could have been inhabited by the
Greeks, though no proof has yet been found. During
Roman times, Cassis was part of the maritime route made by the Emperor
Antoninus Pius. It was a small village, established mainly around the Arena and Corton beaches. The principal livelihood was fishing and maritime trade with
North Africa and the
Middle East. Several archaeological discoveries attest to this. From the 5th to the 10th centuries AD,
invasions by foreign tribes led the population to seek refuge in the
castrum, a fortified city that, in 1223, became the property of the Seigneurie des
Les Baux-de-Provence. In the 15th century, Cassis was ceded to the
Counts of Provence; then
René of Anjou gave the town to the Bishops of Marseille, who ruled the town until the
Revolution of 1789. ==Industrial Revolution==
