Church of El Salvador
The church of El Salvador occupies the building of a previous mosque, probably dating from the 11th century. The mosque itself was built on the remains of a sacred Visigothic building. The conversion to Christian worship in 1159 brought about various modifications, including the construction of the Gothic chapel of St Catherine at the end of the 15th century. A brick bell tower was then added to the minaret, inlaid with friezes, which was transformed into a bell tower.
