The Great Mosque of Muhammad Ali Pasha, also known as the Alabaster Mosque, is a mosque located in the Citadel of Cairo, Egypt. It was commissioned by Muhammad Ali Pasha after building was completed in 1848. Situated atop the citadel, this Ottoman mosque is noted to be the largest built in the first half of the 19th century. With its animated shadows and twin minarets, the mosque is one of the most visible monuments in this Egyptian city. It was built to honour Tushu Pasha, Muhammad Ali’s oldest son. The mosque was constructed with a middle dome surrounded by four smaller semicircular domes. The Central dome is 21m in diameter and the height of the building stands at 52m. The main material of the mosque is limestone though the bottom floor and forecourt is tiled with alabaster. A brass clock tower sits in the middle of the northwestern riwak - presented to Muhamad Ali by King Louis Philippe of France in 1845. A stunning piece of architecture, it certainly cannot be missed if you happen to be in Cairo.
