Mersin (İçel) is Turkey's largest port by trade volume, but its coastline beyond the city is one of the most dramatic on the Mediterranean: a string of Crusader castles, sunken cities, ancient harbours and cliff-fringed coves stretching to the Syrian border. Kızkalesi — a 12th-century sea castle accessible by boat — is its signature image.
Tarsus, within the province, was the birthplace of the Apostle Paul and a Hellenistic and Roman city of note; ancient Tarsus's waterfall, Roman road and Cleopatra's Gate still stand in the modern city.
