Cartagena is a Spanish city and a major naval station located in the Region of Murcia, by the Mediterranean coast, south-eastern Spain. Much of the historical weight of Cartagena in the past goes to 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 there is a big naval shipyard.
