Olba, later Diocaesarea, is an ancient Seleucid city in Rough Cilicia in Turkey’s rugged Eastern Mediterranean coastline. In the Hellenistic period, the city was the centre of worship of Zeus Olbios whose sanctuary was located about 4 km to the west. Erected during the reign of the Seleucids, the temple, Corinthian in style, is the oldest peripteral temple (6×12 columns) in Asia Minor. Other monuments from the Hellenistic period include a 22m-high tower and a mausoleum. The Roman city of Diocaesarea later developed in the 1st century AD around the temple devoted to Zeus Olbios and its ruins today lie partly within the grounds of the village of Uzuncaburç (Turkish for high tower and referring to the Hellenistic tower) and its immediate surroundings.
The most important Roman buildings on the site date from the 1st to the 3rd century AD and include a theatre, a nymphaeum, an aqueduct, and many tombs dug in the rock. The city is entered through a monumental gate, of which five columns have survived. Then a colonnaded street runs alongside the temple of Zeus Olbios and leads to the temple of Tyche. To the north-west, a three-arched Roman gate leads out of town.
Lixus is an ancient Roman-Berber-Punic city on the western coast of Morocco, just north of Larache. It lies on a hill with spectacular views over the Loukkos Estuary (Lucus River) and is one of the first western Mediterranean’s cities. Lixus was first settled by the Phoenicians during the 8th century BC and gradually grew in importance as a trading post (in gold, ivory and slaves), later coming under Carthaginian domination. After the destruction of Carthage, the city fell to Roman control and reached its zenith during the reign of the emperor Claudius (AD 41–54) and began exporting the fish-based garum sauce. The salt-fishing factory consisted of closely-spaced complexes with a salting capacity of over one million litres, making it the largest garum producer in the western Mediterranean. In the 3rd century AD, Lixus became nearly fully Christian. The site was abandoned in the 7th century AD and later became known to Muslims as Tuchummus when a mosque was erected.
Floors decorated in mosaics, an amphitheatre, garum-making facilities, baths, and a Paleochristian church are reminders of the splendour and prosperity of Lixus. The excavated zones (62 hectares) constitute approximately 20% of the total surface of the site.
