Cádiz

You could write several weighty tomes about Cádiz and still fall short of nailing its essence. Cádiz is generally considered to be the oldest continuously inhabited settlement in Europe, founded as Gadir by the Phoenicians in about 1100 BC. Now well into its fourth millennium, the ancient centre, surrounded almost entirely by water, is a romantic jumble of sinuous streets where Atlantic waves crash against eroded sea walls, cheerful taverns fry up fresh fish and salty beaches teem with sun-worshippers.
