English: The city of Marrakesh was captured by Almohads after the death of the Almoravid leader Ali ibn Yusuf in 1147. The Almohads did not want any trace of religious monuments built by the Almoravids, their staunch enemies, as they considered them heretics. Abd-al-Mu'min, who won the territory, was responsible for building the first Koutoubiya mosque on the grounds of the former palace of Ali ibn Yusuf in the southwest quarter of the medina. This first mosque was built between 1147 and 1154 and completed in 1157. This initial mosque was rebuilt under the Almohad Caliph Yacoub El-Mansour, as it was realized halfway through construction that the mihrab (prayer niche) was misaligned and not oriented towards Mecca, and underwent many changes until the end of the 12th century, when the Andalusians defeated the Almohad dynasty. The alignment problem was a minor issue, as devotees could always adjust the direction when offering prayers in the hall, but the decision was taken to build a new mosque alongside the first structure. The first mosque was completed while the second mosque was undergoing construction. The second mosque was built identical to the first except for its orientation. The layout, architectural designs, inscriptions, dimensions and materials used for construction were all the same. The minaret plan and design remained the same in both buildings. While in the first mosque, the orientation of the mihrab was 5 degrees out of alignment with respect to the direction towards Mecca, in the second mosque, the orientation was 10 degrees off, thus actually further out of alignment with Mecca than the first mosque.
