Up until the reign of Abdellah El Ghalib Jews were relatively dispersed through the city but the area of Mouassine housed a significant concentration of them and was generally regarded as an ancient Jewish quarter.[4] When Abdallah El Ghalib came to power in 1557 he used the opportunity to re-landscape Marrakech as a symbol of his authority and part of this was to relocate the Jewish community into the new Mellah area. Up until this massive re-landscaping Mouassine was regarded as one of the two ancient Jewish areas.[5] The most famous landmark in Mouassine is the Mouassine Mosque commissioned by Sultan Abdellah.[6] The construction of the mosque was part of a major redevelopment of the area and was located upon the site of a former Jewish cemetery.[7] The mosque, also known as Jami' al-Ashraf is part of a larger complex that includes a library, hamman, madrasa and the famous Mouassine Fountain, one of the most famous in the medina.[8]
