The Roman city was built on three small hills which overlooked the sea, nearly 20 km. east from Caesarea (capital of Mauretania Caesariensis). Of the houses, most of which stood on the central hill, no traces remain; but there are ruins of three churches — the Great Basilica and the Basilica Alexander on the western hill, and the Basilica of St Salsa on the eastern hill, two cemeteries, the baths, theatre, amphitheatre and nymphaeum. The line of the ramparts can be distinctly traced and at the foot of the eastern hill the remains of the ancient harbour.
