The mausoleum is a square chamber which holds the tombstones (mqabriyas) of Moulay Isma'il (died 1727), his son and successor Ahmad ad-Dhahabi (died 1729), and the later sultan Moulay Abd ar-Rahman ibn Hisham (died 1859). On the south side of the mausoleum is another large reading room divided by a triple-arched arcade and containing book cabinets. Each of these chambers is covered with carved stucco decoration and also holds several bronze chandeliers.[1][2] The royal tombstones are made of marble and are richly carved with Arabic calligraphic inscriptions and arabesque motifs in a style similar to the marble tombstones of the Saadian Tombs.[3] The tomb chamber also holds two grandfather clocks which were gifts from King Louis XIV of France.[2] The mausoleum is still visited today by Moroccans seeking baraka from Moulay Isma'il's tomb, in addition to being a significant tourist attraction in the city.[2][5][39]
