The Ermita del Cristo de la Luz is located in Toledo, Spain. It is a replica of the original mosque known as Bab-al-Mardum or Cristo de la Luz Mosque. The architecture of the mosque exhibits a blend of Hispano-Muslim and Mudéjar styles.
The main facade features three arches in Arab, Byzantine, and lobed styles, adorned with a blind gallery and a brick decoration in a herringbone pattern. The eastern facade also has three Arab arches with rounded overarches, and the second level showcases a beautiful blind gallery with six horseshoe arches and trilobed overarches.
The exterior of the mosque is predominantly made of exposed brickwork. The northern facade follows a similar pattern with three arches in Arab, Byzantine, and lobed styles, decorated with intersecting arches and a herringbone brick pattern.
The mosque has a three-aisled floor plan, and in the apse, there is a niche known as the mihrab, which was the former Muslim prayer niche. According to legend, while Alfonso VI was riding his horse in front of the mosque, he was struck by a dazzling light, leading to the discovery of a Christ figure, hence the name “Cristo de la Luz” (Christ of the Light). The Christ figure gained great devotion, but it was later desecrated with poison at its feet.
