Gibraltar

Gibraltar, British overseas territory (2005 est. pop. 27,900), 2.5 sq mi (6.5 sq km), on a narrow, rocky peninsula extending into the Mediterranean Sea from SW Spain. Most of the peninsula is occupied by the Rock of Gibraltar (Lat. Calpe ), one of the Pillars of Hercules , which guards the northeastern end of the Strait of Gibraltar, linking the Mediterranean with the Atlantic. The town of Gibraltar lies at the northwest end of the Rock of Gibraltar. The peninsula is connected with the mainland by a low sandy area of neutral ground. West of the peninsula is the Bay of Gibraltar, an inlet of the strait. There is a safe enclosed harbor of 440 acres (178 hectares). The rock, of Jurassic limestone, contains caves in which valuable archaeological finds have been made. It is honeycombed by defense works and arsenals, which are largely concealed. A tunnel bisects the rock from east to west.
