The 12C minaret of the former mosque, a masterpiece of Almohad art, is the emblem of Seville. In the 16C the Córdoba-born architect Hernán Ruiz was charged with its transformation. He added balustrades to the openings and perched a weather vane (giralda) on a platform on the bell tower, hence the name of this 100m-tall structure. The panoramic view over Seville makes it worth the effort of climbing up.
