Almería (Spanish: [almeˈɾi.a]) is a city in Andalusia, Spain, located in the southeast of Spain on the Mediterranean Sea, and is the capital of the province of the same name. It was Abd-ar-Rahman III who founded the Alcazaba (the Citadel), which gave this city its name: Al-Mari'yah (المريّة, the Watchtower). In the 10th and 11th centuries, it formed part of the Caliphate of Córdoba, and grew wealthy on trade and the textile industry, especially silk. It suffered many sieges and fell under Christian domination in 1489. In 1522, Almería was devastated by an earthquake and rebuilding and recovery didn't really get underway until the 19th century. During the Spanish Civil War, the city was shelled by the German Navy, and fell to Franco in 1939. It has since rebuilt its economy around vegetable production, with 100,000 acres of greenhouses, supplying much of Europe.
