The Muhammad Ali Mosque is built after the Blue Mosque in Istanbul and it is known as The Alabaster Mosque because of the decoration of its facade. It was built between 1830 and 1848. Initially the French architect Pascal Coste was hired but then for unknown reason, Mohamed Ali changed his mind and hired Yusuf Bushnaq as an architect of the mosque.
