The place behind the detail.

The Almoravid ruler Ali ibn Yusuf built the koubba beside the Ben Youssef Mosque, then the main mosque of Marrakech. It is generally understood to have been part of the mosque’s ablutions facility, where worshippers washed before prayer.

The domed pavilion is small, about 7.35 by 5.45 metres and 12 metres high, built of stone, brick and cedar wood, and it shelters a water basin. Beside it are the remains of a fountain open to the street, a vaulted cistern and a series of latrines.

Inside, the cupola is carved with pine cones, palms, acanthus leaves, shells and palmettes, and it has been compared to the domes of the Great Mosque of Córdoba and the Bab al-Mardum Mosque in Toledo.

Small cupolas in the four corners carry some of the earliest muqarnas in Morocco. A damaged Arabic inscription runs around the interior and names Ali ibn Yusuf; its year can no longer be read, so the koubba is dated to 1117 or, more likely, 1125.

The Almohads, who took Marrakech in 1147, destroyed most Almoravid monuments. Buried for centuries under rising ground and uncovered by archaeologists in the mid-20th century, the koubba is one of the few buildings to survive from Almoravid Marrakech.
