The mausoleum, a veritable royal funerary complex to the south of Mulay Isma'il's palace, was built near to the burial site of the saint Sidi 'Abd al-Rahman al-Majdub, a mystic of the AH 10th / AD 16th century.
Restored by Sultan Mulay Isma'il's successors, the building has a complex layout of Hispano-Maghrebi influence, complete with zellij (small tile) and stucco decoration, in which the structural elements are arranged in a row, similar to three rooms of the Rauda at the Alhambra in Granada, Spain.
The sultan's tomb is at the centre of the complex. A mihrab linked to the courtyard and burial rooms was constructed for prayers.
