Taranto is a coastal city in Apulia, Southern Italy. It is the capital of the province of Taranto, serving as an important commercial port as well as the main Italian naval base. Founded by Spartans in the 8th century BC during the period of Greek colonisation, Taranto was among the most important poleis in Magna Graecia, becoming a cultural, economic and military power that gave birth to philosophers, strategists, writers and athletes such as Archytas, Aristoxenus, Livius Andronicus, Heracleides, Iccus, Cleinias, Leonidas, Lysis and Sosibius. The ancient city was situated on a peninsula; the modern city has been built over the ancient Greek city of which only a few ruins remain, including part of the city wall, two temple columns dating to the 6th century BC, and tombs. By 500 BC, the city was among the largest in the world, with a population estimated up to 300,000 people. During the Norman period, it became the capital of the Principality of Taranto, which covered almost all of the heel of Apulia.
