The Djinguereber Mosque (Masjid) in Timbuktu is a famous learning center of Mali built in 1327, and cited as Djingareyber or Djingarey Ber in various languages. Its design is accredited to Abu Es Haq es Saheli who was paid 200 kg of gold by Mansa Kankan Musa, emperor of the Mali Empire. According to Ibn Khaldun, one of the best known sources for 14th century Mali, says al-Sahili was given 12,000 mithkals of gold dust for his designing and building of the djinguereber in Timbuktu.
Except for a small part of the northern facade, which was reinforced in the 1960s in alhore (limestone blocks, also widely used in the rest of the town), and the minaret, also built in limestone and rendered with mud, the Djingareyber Mosque is made entirely of earth plus organic materials such as fibre, straw and wood. It has three inner courts, two minarets and twenty five rows of pillars aligned in an east-west direction and prayer space for 2,000 people.
