Andalusian Mosque

The Andalusian Mosque (Mosque of the Andalusians) is a major historic mosque in Fes el-Bali, the old medina quarter of Fez, Morocco. It takes its name from the district around it, which was historically associated with Andalusi immigrants, and it stands on the Andalusian bank (Adwat al-Andalus) of the Fez river valley. Founded in 859, it is among the oldest mosques in the country and is one of the relatively few surviving establishments from the Idrisid era. It is regarded as one of the main landmarks of the city. The building has been renovated and expanded several times over the centuries, and it forms part of a World Heritage site.

The mosque was founded in 859–860. Arabic-language sources credit its construction in 859 to Maryam al-Fihriya. The minaret was added in 956. Most of the building was reconstructed between 1203 and 1207 under the Almohads, and the Arabic source links the mosque's present boundaries to this period.

The Marinids later added a fountain in the courtyard and a library. Under the Alaouites, Moulay Ismail ordered a renovation. Further additions and restorations were carried out at other times. The mosque's original 10th-century minbar has survived and is displayed at the Dar Batha Museum in Fez.
