The Mosque of Cristo de la Luz is a former mosque in Toledo, Spain. It is the one of the ten that existed in the city during the Moorish period. The edifice was then known as Mezquita Bab-al-Mardum, deriving its name from the city gate Bab al-Mardum. It is located near the Puerta del Sol, in an area of the city once called Medina where wealthy Muslims used to live.
