The ornate carved headstones in the inner room of the mausoleum merely indicate the location of the actual tombs in a crypt directly underneath the main chamber. Under Ulugh Beg's government a solid block of dark green jade was placed over the grave of Tamerlane. Formerly this stone had been used at a place of worship in the Chinese emperor's palace, then as the throne of Duwa (a descendant of Genghis Khan) in Chagatay Khanate. Next to Tamerlane's grave lie the marble tombstones of his sons Miran Shah and Shah Rukh and also of grandsons – Muhammad Sultan and Ulugh Beg. Tamerlane's spiritual teacher Mir Said Baraka, also rests here.
