Algeciras

The area was inhabited in Antiquity, including archaeological strata generally identified with the Roman city of Iulia Traducta. Founded soon after the Islamic conquest of the Iberian Peninsula on the mouth of the Río de la Miel, al-Jazira al-Khadrā became the head of a rump taifa kingdom after Umayyad state collapse in the 11th century. In 1275, the Emirate of Granada ceded the place to the Marinids, who founded the new walled precinct of al-Bunayya after 1282 on the opposite bank of the Río de la Miel. The twin medinas were conquered in 1344 by the Crown of Castile. Medieval urban continuity came to an abrupt end when the town was torn down by the Nasrids circa 1369–1385. The ruins were repopulated and the town eventually refounded upon the arrival of refugees from the 1704 Anglo-Dutch capture of Gibraltar.

The Port of Algeciras is one of the largest ports in Europe and the world in three categories: container, cargo and transshipment. The surrounding metropolitan area also includes the municipalities of Los Barrios, La Línea de la Concepción, Castellar de la Frontera, Jimena de la Frontera, San Roque and Tarifa, with a population of 263,739.
