Cartagena (Spanish pronunciation: [kaɾtaˈxena]) is a Spanish city and a major naval station on the Mediterranean coast, south-eastern Iberia. As of January 2018, it has a population of 218,943 inhabitants. This makes Cartagena Murcia's second-largest municipality and Spain's sixth-largest city that is not a provincial-capital. The wider urban or metropolitan area of Cartagena, known as Campo de Cartagena, has a population of 409,586 inhabitants.
Cartagena has been inhabited for over two millennia, being founded around 227 BC by the Carthaginian Hasdrubal the Fair as Qart Hadasht (Phoenician: 𐤒𐤓𐤕𐤟𐤇𐤃𐤔𐤕 QRT𐤟ḤDŠT; meaning "New Town"), the same name as the original city of Carthage. The city had its heyday during the Roman Empire, when it was known as Carthago Nova (the New Carthage) and Carthago Spartaria, capital of the province of Carthaginensis.
Much of the historical significance of Cartagena stemmed from its coveted defensive port, one of the most important in the western Mediterranean. Cartagena has been the capital of the Spanish Navy's Maritime Department of the Mediterranean since the arrival of the Spanish Bourbons in the 18th century. As far back as the 16th century it was one of the most important naval ports in Spain, together with Ferrol in the North. It is still an important naval seaport, the main military haven of Spain, and is home to a large naval shipyard.The confluence of civilizations, its strategic harbor, and the influence of the local mining industry have led to a unique historic, architectural and artistic heritage. This heritage is reflected in a number of landmarks of Cartagena, including the Roman Theatre, an abundance of Phoenician, Roman, Byzantine and Moorish remains, and a plethora of Art Nouveau buildings from the early 20th century. Cartagena is now established as a major cruise ship destination in the Mediterranean and an emerging cultural focus.
It was the first of a number of cities that have been named Cartagena, most notably Cartagena, Colombia.
