The former Moorish-style mosque was built in the middle of the 11th century[1] on the foundations of Roman architecture, located in the old Muslim neighborhood Arrabal de Francos.

The building continued maintaining the Islamic faith in Spain well beyond the reconquista of the city by the Christian troops of Alfonso VI of León and Castile in 1085, until the period of 1498–1505, when it was desacralizated by the Catholic Monarchs.

Its history was lost until the late 19th century, when historians investigating its origins didn't know whether it was a synagogue or a mosque.

After the studies, on 15 March 1905, the finding of an Arab mosque in the street of the Tornerías was officially communicated to the Real Academia de la Historia.

The ground floor, which is accessed from the street of the Tornerías, opens to the Roman water tanks with granite half-point arches.
