Origin: Built during the Almohad period (12th-13th centuries), as part of Niebla's defensive system. Legend of the name: During the siege by Alfonso X the Wise (1262), the last Muslim king of Niebla, Aben-Mafot, sent a fattened ox out through this gate to create the illusion of abundant provisions and discourage the Christian troops. The stratagem failed, and the city was conquered.
