Al Anwar Hanging Mosque

The Al-Anouar Mosque (jama' al-anwar, lit. 'Mosque of the Lights'), formerly also known as the Mosque of the Sheikhs (jama' al-ashiakh, "Mosque of the Chiefs"), was the oldest mosque in Fez, Morocco. It was founded by Idris I at the same time as he founded the city itself, in the early 9th century. It was located slightly northeast of the current Mosque of the Andalusians, which surpassed it as the main mosque of the area. Today only remnants of the mosque have survived.
