The mosque and mausoleum of Sayyida Zainab stands in the heart of a square in Cairo, named after Sayyida Zainab. Most historians believe that she was buried in Damascus (Syria) but according to the Fatimid rulers of Egypt, in her last days she lived and passed away in Cairo. According to her will she was buried in the same place where she had lived for about eleven months in al-Fustat (Old Cairo).
The very first mosque on this site was built during the reign of Sultan Ahmed Ibn Tulun. This mosque has gone through many renovations in the past. The last expansion was carried out during the reign of President Hosni Mubarak. The whole area of the mosque is erected on columns made of white marble and it adds beauty and space to this structure.
