Exterior close-up of the Mohamed Ali Mosque (Alabaster Mosque) at the Salah El-Din Citadel in Cairo, Egypt, showcasing the mosque's characteristic Ottoman-style tiered domes in white and brown stone, flanked by four tall pencil minarets. Built between 1830 and 1848 during the reign of Mohamed Ali Pasha, the mosque is modeled after the Sultan Ahmed Mosque in Istanbul and remains one of Cairo's most iconic landmarks. The low-angle shot from the citadel's outer stone wall emphasizes the monumental scale and architectural grandeur of the structure.
