Modelled on classic Ottoman lines, with domes upon domes upon domes, this alabaster-white mosque within the Citadel took 18 years to build (1830–48) and its interior is all twinkling chandeliers and luridly striped stone, the main dome a rich emerald green. Mohammed Ali lies in the tomb on the right as you enter.
The glitzy clock in the entrance courtyard was a gift from King Louis-Philippe of France in return for the obelisk that adorns the Place de la Concorde in Paris, but it arrived damaged and was never repaired.
