The port city of Cartagena, Mediterranean coast of southeastern Spain

 “A ship in port is safe; but that is not what ships are built for. Sail out to sea and do new things.” — Admiral Grace Hopper

============================
(on the Mediterranean coast of southeastern Spain) The port city of Cartagena, the site of Spain’s chief Mediterranean naval base, features the finest harbor on the country's east coast; a deep spacious bay, it is dominated to seaward by four hills crowned with forts and approached by a narrow entrance guarded by batteries. A Roman amphitheater, Moorish castle, and the bombed-out ruins of a 13th-century cathedral are just some of the major sights in history-laden Cartagena. Complemented by its great beaches, pulsating nightlife, and mountainous surroundings, Cartagena proves to be one of southern Spain’s most vibrant and varied cities. The city's natural harbor has been used for thousands of years. Stand on the battlements of the castle overlooking it and you will behold multiple layers of history spread below you: the wharf where Phoenician traders docked their ships; the street where Roman legionaries marched; the plaza that once housed a mosque; the hills over which marched the armies of the Christian Reconquista; the factories of the industrial age; the Modernista buildings; and the contemporary warships of the naval base.
