The great Mosque of Muhammad Ali Pasha - the mosque was built on the site of old Mamluk buildings in Cairo's Citadel between 1830 and 1848, although not completed until the reign of Said Pasha in 1857. Before completion of the mosque, the alabastered panels from the upper walls were taken away and used for the palaces of Abbas I. The stripped walls were clad with wood painted to look like marble. In 1899 the mosque showed signs of cracking and some inadequate repairs were undertaken. But the condition of the mosque became so dangerous that a complete scheme of restoration was ordered by King Fuad in 1931 and was finally completed under King Farouk in 1939.
