for two names that are carved on the bases of two of the cupolas: Ibrāhīm and Salāma ibn Mufarrij, who may have been of Andalusi origin. Lastly, a new minbar in similar style and of similar artistic provenance as the minbar of the Koutoubia Mosque was completed and installed in 1144. It is made of wood in an elaborate work of marquetry, and decorated with inlaid materials and intricately carved arabesque reliefs. Its style was emulated for later Moroccan minbars. Elsewhere, many of the mosque's main entrances were given doors made of wood overlaid with ornate bronze fittings, which today count among the oldest surviving bronze artworks in Moroccan architecture. Another interesting element added to the mosque was a small secondary oratory, known as the Jama' al-Gnaiz ("Funeral Mosque" or "Mosque of the Dead"), which was separated from the main prayer hall and dedicated to providing funerary rites for the deceased before their burial. The annex is also decorated with a muqarnas cupola and ornate archways and windows. Almohad period (12th–13th centuries) Later dynasties continued to embellish the mosque or gift it with new furnishings, though no works as radical as the Almoravid expansion were undertaken again. The Almohads (later 12th century and 13th century) conquered Fez after a long siege in 1145–1146. Historical sources (particularly the Rawd al-Qirtas) report a story claiming that the inhabitants of Fez, fearful that the "puritan" Almohads would resent the lavish decoration placed inside the mosque, used whitewash to cover up the most ornate decorations from Ibn Yusuf's expansion near the mihrab. Terrasse suggests this operation may have actually been carried out a few years later by the Almohad authorities themselves. The Almoravid ornamentation was only fully uncovered again during renovations in the early 20th century. The plaster used to cover the Almoravid decoration seems to have been prepared too quickly and did not fully bond with the existing surface. This ended up making its removal easier during modern restorations and has helped to preserve much of the original Almoravid decoration now visible again today. Under the reign of Muhammad al-Nasir (ruled 1199–1213) the Almohads added and upgraded a number of elements in the mosque, some of which were nonetheless marked with strong decorative flourishes. The ablutions facilities in the courtyard were upgraded, a separate ablutions room was added to the north, and a new underground storage room was created. They also replaced the
