Mohamed Ali Mosque is located in the Citadel of Saladin, which was built by Sultan Saladin 
Built between 1830 and 1848, the Ottoman-style Mohamed ‘Ali Mosque or Alabaster Mosque is the most noticeable in all of Cairo. for more than 150 years it has dominated the skyline with its animated silhouette and twin minarets, making it one of the most visible mosques in Cairo.
The 19th century islamic monument holds 
an impressive interior because of its enormity, and showing off 
wonderful arrangement of mass and space that is a characteristic of 
Istanbul mosques. The main, high dome of the mosque soars 52 meters 
high, with a diameter of 21 meters.
The grandeur of this single, large 
chamber is enhanced by a circle of small lamps hung in the middle of the
 praying area, and just above the main dome of the mosque. Other smaller
 lamps, are spread elsewhere in the mosque, creating a spectacle of 
light that is grand in its own right.
