The mausoleum's interior consists of a tall sanctuary ornamented with designs in facets of mirror beneath the dome, and the tomb, as in the other places of pilgrimage in Shiraz, is situated in an alcove on the northern side, and there is a mosque adjacent to the sanctuary behind the railing of the tomb. The original building of the mausoleum was constructed by Qotlogh Khan, who in the Ilkhanate and Timurid period, at the close of the fourteenth, or at the beginning of the fifteenth century, was Governor of Shiraz, and had a garden where the present mausoleum stands, which was built over the site where the grave appeared to be.
