On the pattern of the Qarawiyyn Mosque in Fez and the architecture from the 'school of Susa'. The decor of the Hutubiyya Mosque introduces the accents of dry functionality typical of Almohad of every element to its essence. The ogival heads confer a powerful yet serrnce sense of thrust onto the horseshoe arches.
The study square minaret, approximately sixty-eight metres high on a base of twelve, formed a prototype for the extraordinary minarets of Seville (such as the famous Giralda) and for the Hassan tower in Rabat. The square shaft is barely lit by a few windows corresponding to the stairway which are therefore asymmetric and framed by vast blind arches of attractive polyfoil tracery which is particularly impressive in the shifting rays of the sun. The upper zone comprisses a blind arcade whose profile unfolds and intersects to form the motif known as a sebka, frequently employed in later achitecture. The band on the stretch of wall above was once decorated with turquoise majolica, while the aedicule at the top recapituates, in miniature, the motifs displayed below.
