Prior to the early 8th century, a Visigoth church stood on this site. Then a Moslem mosque was built here in a district then called al-Mugira. After Ferdinand III conquest in 1236, the property was given to Christians and dedicated to Saint Lorenzo Ruiz. The Moorish minaret was converted into a Romanesque bell tower by Hernán Ruiz the Younger during the 16th century. Iglesia de San Lorenzo’s elaborate rose window (called a rosetón in Spanish) is a feature of several Fernandine Churches in Córdoba. However, the portico formed by three arches is fairly unique.
