The Almoravid Qubba is situated next to the Marrakech Museum and around 40 meters south of the Mosque of Ben Youssef. It is the only surviving example of Almoravid architecture in Marrakesh. It was built in either 1117 or, more likely, in 1125, by the Almoravid amirAli ibn Yusuf. Most scholars today believe that it belonged to the nearby Ben Youssef Mosque, the main mosque of the city at the time, and that it was a pavilion used for ritual ablutions before prayer. The mosque itself, also originally built by Ali ibn Yusuf, has since been completely rebuilt in more recent centuries. This type of structure for providing water near a mosque was also known as a mida'a and is found in later mosques in Marrakech. The domed structure also had a system of toilets, showers, and faucets for drinking water. It was rediscovered in 1948 and excavated in 1952, after having been buried beneath one of the outbuildings of the Ben Youssef Mosque.
Description
The domed pavilion
The dome tops a rectangular building, measuring 7.35 by 5.45 meters, sheltering a water basin. Materials used include stone, brick, and cedar wood. The interior is richly decorated with carved floral and vegetal patterns, palmette/seashell shapes, and calligraphy. Its cupola has been compared to the domes of the Great Mosque of Cordoba and the Bab al-Mardum Mosque in Toledo. In the corners, between the wings of the cupola and the rectangular outer walls, are four miniature cupolas carved with some of the earliest muqarnas decoration in Morocco. Since muqarnas decoration would have originated in Abbasid architecture in the Middle East, at least one scholar has suggested that this combination of Cordoban Ummayyad and Abbasid motifs was a deliberate stylistic choice by the Almoravid ruler to invoke a shared legacy and heritage with these caliphates. Around the interior of the pavilion is an Arabic inscription, now badly damaged, which details the foundation of the structure and cites the name of Ali ibn Yusuf and the date of construction, although the year of the date is unfortunately unreadable.
Other structures around the pavilion
A series of private latrines, possibly built at a later period, have also been excavated all around the domed building. Next to the domed building was also a monumental fountain or water source in another rectangular structure measuring around 14.5 by 4.5 meters. The structure was open to the street via three arched openings, with each bay occupied by a water basin and a water trough along its back wall. This fountain structure is reminiscent, in its basic form, of later wall fountains of Marrakech like those of the Mouassine Mosque or of the Shrob ou Shouf Fountain. The water for this fountain and the ablutions kiosk was drawn via bronze pipes from a nearby cistern covered by a barrel vault, which can be found today behind these structures. The supply of water to this cistern probably relied in turn on the revolutionary hydraulics of khettaras, a drainage system characteristic of historic Morocco.
