According to some traditions, these are the Mazarat of brothers of Hazrat Yousuf (Joseph) (Peace be upon him). Only the main dome is now intact. Beneath it is a triple mihrab surrounded with Fatimid-style calligraphy and decoration. Some evidence of a burial site is extant just to the west of the dome. The site is located in the Southern Cemetery in Cairo just north of the Lu'lu' Mosque.
