Philippeville occupies the site of successive Phoenician and Roman cities By the Romans, under whom it attained a high state of prosperity, it was named Rusicada. In the middle ages the town ceased to be inhabited The site was purchased from the Arabs by Marshal Valée in 1838 for £6 Some parts of the Roman theatre remain, but the stones of the amphitheatre, which stood without the walls of the modern town, and which the French found in an almost perfect state of preservation, were used by them for building purposes, and the railway was cut through the site. On a hill above the tow11 are the Roman reservoirs, which have been restored and still supply the town with water. They are fed by a canal from the Wadi Beni Meleh. The Roman baths, i11 the centre of the modern town, serve as cellars for military stores.
