Yusuf ibn Tashfin
Djamaa el Kebir ("Jamaa-el-Kebir" الجامع الكبير) is the oldest mosque in Algiers. It was first built by Yusuf ibn Tashfin, but reconstructed many times. The pulpit ("minbar" منبر) bears an inscription showing that the building existed in 1097. The minaret was built by the sultan of Tlemcen, in 1324. The interior of the mosque is square and is divided into aisles by columns joined by Moorish arches.
