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.

The route is nice but it is better to start in Trigueros if you are going with a hybrid or gravel bike, up to there the terrain is very bad and there is nothing remarkable from San Juan del Puerto.

The originally Romanesque church was initially a tolerated Christian church during the Moorish period. This later became the main mosque of Lepla, as the place was called at that time. Today's bell tower was the minaret. An Islamic mihrab (prayer niche) has been preserved in the church as well as a stone bishop's chair from the city's Visigothic era. Through renovation work in the 16th century, the church received Gothic elements with references to the Mudejar style. Unfortunately the church is usually closed.
