Cartagena (Spain)
Today Spain's major commercial port and naval base, Cartagena lies on the coast of Murcia, its great indented bay guarded by rocky promontories, each topped by a fort. The city contains the remains of old walls, a castle constructed probably in Carthaginian times, and a church that was formerly a 13th-century cathedral. Attractive promenades extend along the harbour, while to the northeast is the famous beach and watersports resort area of the lagoon-like Mar Menor.
