The Bay of Gibraltar (Spanish: Bahía de Algeciras), is a bay at the southern end of the Iberian Peninsula. It is around 10 km (6.2 mi) long by 8 km (5.0 mi) wide, covering an area of some 75 km2 (29 sq mi), with a depth of up to 400 m (1,300 ft) in the centre of the bay. It opens to the south into the Strait of Gibraltar and the Mediterranean Sea. The shoreline is densely settled. From west to east, the shore is divided between the Spanish municipalities of Algeciras, Los Barrios, San Roque, La Línea de la Concepción and the British Overseas Territory of Gibraltar. The larger part of the shoreline is Spanish territory, with part of the eastern half of the bay belonging to Gibraltar.[1] The east and west entrances to the bay are marked respectively by the Europa Point Lighthouse at Europa Point, Gibraltar and the Punta Carnero Lighthouse in Punta Carnero to the west of Algeciras.
