Cádiz is the modern name for ancient Gades considered the original kingdom of Gadeirus the twin brother of Atlas. However, the certainty normally associated with this accepted identification is weakened by the fact that quite a number of locations with similar sounding names are to be found in the Central and Western Mediterranean regions.
It is generally accepted that the Phoenicians from Tyre founded Gadir, later to be known as Gades to the Romans. The Roman historian, Velleius Paterculus (c.19 BC – c.31 AD) wrote that Cadiz was founded 80 years after the Trojan War, circa 1100 BC. In the 9th century BC, the Phoenicians, under Princess Dido, founded a new capital at Carthage in North Africa. At Gades the Phoenicians/Carthaginians built a temple to Melqart that had two columns that many consider to be the original Pillars of Hercules. In 2007, it was announced that excavations in the old town centre produced shards of Phoenician pottery and walls dated to the 8th century BC, probably making it the oldest inhabited city in Europe.
