The current church is built on an old Muslim mosque, so it is oriented southeast, towards Mecca. For which construction, as was usual, different Visigothic architectural elements were reused, thanks to which a horseshoe arcade supported on Visigothic pilasters has been preserved with sculpted decoration of figurative themes, unusual in this type of remains. The Pilaster of El Salvador, presents on one of its faces various miraculous scenes from the life of Jesus, in overlapping records: the Cure of the Blind, the Resurrection of Lazarus, the Samaritan and the Hemorroísa, as well as other themes of eucharistic hue that allude To Christ as salvation and whose iconography seems to be taken up from some Early Christianity sarcophagus that could serve as a model. Its crude treatment shows the abandonment in which the work had fallen on the stone.
