its initial construction. In 1860 it was finally torn down altogether and replaced with a flat wooden roof, as it is today. The lower walls of the mausoleum are covered in marble dadoes topped by a calligraphic frieze of black letters inset into marble, similar to the one found in the mosque. Unlike the mosque's version, however, the calligraphy here is a in a fine thuluth script. In addition to this, the chamber features a series of calligraphic compositions carved into vertical black marble panels along the walls, unprecedented in Mamluk art. They include compositions in a mirror configuration as well as in the shapes of vases, trees, and stylized birds. Another marble-decorated mihrab is located in the western wall, again with its own pattern different from the other mihrabs of the complex. On either side of the mihrab are wooden cupboards whose interiors are delicately painted with floral and interlacing patterns. It was likely here that the relics of Muhammad were once kept. The rest of the walls above the marble dadoes are covered in shallow arabesque reliefs, another remarkable feature of the hall. The transition zone between the square chamber and the round dome is achieved through four very long pendentives carved with muqarnas. Because al-Ghuri's body was never found after the Battle of Marj Dabiq (1516), the sultan's body is not buried here. Some of his family members were buried here, including his daughter in 1505, followed by his 13-year-old son (Nasir al-Din Muhammad) and his mother. Sultan Tumanbay, who reigned briefly after his death until the Ottomans arrived in Cairo and executed him, was also buried here.
