The crumbling, sun-baked seafront city of Cádiz is said to be the oldest continuously inhabited settlement in the western world, founded by the Phoenicians around 1100 BC.

Sovereignty of ‘The Rock’ has been a thorny issue ever since Gibraltar was ceded to Britain in 1713, though on the ground it’s clear where most locals’ sympathies lie.
