The old city of Phœnicians and Phocœans occupied that portion of the present town lying between the sea and the ancient port, and the walls cut across from the Anse de la Joliette, mounted the Butte des Carmes and descended to the head of the Vieux-port. The Butte des Moulins was the Acropolis, and on it stood temples of the gods of Carthage and Greece. The sea-face was formerly very different from what it is now. Cæsar speaks of Marseilles being washed by the sea on three sides. The sea has eaten away a very large portion of the peninsula. The cathedral, La Major, was not formerly on the quay; till the end of the eighteenth century its principal portal faced the sea. At the close of that century, so much of the town having been washed away, and so sapped was the rock on that side, that a doorway had to be opened on the landside. An old chapel existing in 1202 stood at a point now 250 feet from the land. Recent works, the formation of a succession of basins, have arrested this degradation of the coast, and have regained some of the lost land. Marseilles lies in an amphitheatre, but this is only realised when the city is approached from the sea. To those arriving by rail it appears to be a town scattered over a series of hills, very irregular and of a very confused plan. All that portion of the town that lies south of the Vieux-port, about the Palais de Justice to where the hill rises, was formerly morass; the houses here have no cellars, and are built, like Amsterdam, on piles. Above the Bassin de Carinage rises the Church of S. Victor, built in the eleventh and extended in the thirteenth century. The towers and ramparts were erected by William de Grimoard in 1350. He had been prior of the monastery of S. Victor, and afterwards became pope under the name of Urban V. All this portion of rising ground to the south of the old harbour seems to have been the refuge of the first Christians. Excavations made in extending the basin laid bare vestiges of catacombs of a very early period, earlier, in fact, in some cases than the Christian era. In the fourth century the monk Cassian founded a monastery above these catacombs. It was destroyed by the Saracens and rebuilt, and became a vastly wealthy foundation. The monastery on one side of the port, and the cathedral with its appurtenances on the other, were not under the jurisdiction of the municipal authorities of Marseilles; but each had its own town of dependencies under separate government. What remains of this famous abbey bears an aspect of a citadel rather than of a church. It is an extraordinary jumble of parts, and from without looks as if it were wholly planless.
