Zaragoza, (English Saragossa). Industrial city (iron, steel, chemicals, plastics, canned food, electrical goods) in Aragon, Spain; population (1996) 596,000. The medieval city walls and bridges over the river Ebro survive, and there is a 15th-century university. history founded as Salduba in pre-Roman days, it took its present name from Roman conqueror Caesar Augustus; later it was captured by Visigoths and Moors and was taken in 1118 by Alfonso the Warrior, King of Navarre and Aragon, after a nine-month siege. It remained capital of Aragon until the end of the 15th century. From June 1808 to Feb 1809, in the Peninsular War, it resisted a French siege. Maria Augustin, known as the `Maid of Zaragoza', died 1859, became a national hero for her part in the defence; her story is told in Byron's Childe Harold 1812-18.
