Cartagena 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 the Murcia region'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, 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 and Carthago Spartaria, capital of the province of Carthaginensis.
