The Giralda (Spanish: La Giralda ; Arabic: الخيرالدة‎) is a bell tower of the Seville Cathedral in Seville, Spain. It was originally built as a minaret during the Moorish period, with a Renaissance style top subsequently added by Spaniards. The Giralda was registered in 1987 as a World Heritage Site by UNESCO along with the Alcazar and the General Archive of the Indies.
