Mers el-Kebir

Algeria

Mers el-Kebir, town and port, northwestern Algeria, situated on the Mediterranean Sea at the western end of the Gulf of Oran. The town was an Almohad naval arsenal in the 12th century. It was under the rulers of Tlemcen in the 15th century and fell to corsairs in 1492. The town was later contested by the Spanish, Portuguese, and Turks until France gained control of it in 1830.

Mers el-Kebir (Arabic: “Great Harbor”) was developed in 1939–56 as a major French naval base. In 1940, during World War II most of the French fleet at anchor there was destroyed by British warships to prevent acquisition by the advancing Germans. Under the terms of the Evian Agreements for Algerian independence in 1962, France was to retain the port for 15 years. Control was relinquished to Algeria, however, in 1968.

Mers el-Kebir lies at the foot of Mount Santon, whose eastern projection forms Mers el-Kebir Point. The port’s natural harbor is sheltered from east winds and protected by breakwaters. Pop. (2008) commune, 16,970.
