Cartagena (Spain)
Lying on the coast of Murcia, Cartagena is still Spain's major commercial port and naval base.
Founded in 221 BC by Hasdrubal, leader of the Carthaginians (hence the name) from North Africa, it has a fascinating history - and as Nova Carthage was long the Romans' principal settlement in their Iberian stronghold. Attractive promenades extend along the harbour, while to the northeast is the famous beach and watersports resort area of the lagoon-like Mar Menor.
