The Siege of the Alcázar in the Spanish Civil War references this castle, which was held by the Nationalist colonel José Moscardó Ituarte against Republican forces. Republican forces captured Moscardó's 24-year-old son Luis, and on 23 July 1936 informed Moscardó that if he did not turn over the alcázar within ten minutes his son would die. When Moscardó did not surrender, Luis was murdered, not immediately but one month later, on 23 August.[2] Alcázar of Seville, on the site of the palace of the Almohad Caliphate called al-Muwarak, was built in the 1360s by Moorish craftsmen in Mudéjar style, and frequently remodeled.
