The Muhammad Ali Mosque or Alabaster Mosque is a mosque situated in the Citadel of Cairo in Egypt and was commissioned by Muhammad Ali Pasha between 1830 and 1848. Situated on the summit of the citadel, this Ottoman mosque, the largest to be built in the first half of the 19th century, is, with its animated silhouette and twin minarets, the most visible mosque in Cairo. The mosque was built in memory of Tusun Pasha, Muhammad Ali's youngest son, who died in 1816. This mosque, along with the nearby Cairo Citadel, are one of the landmarks and tourist attractions of Cairo

Al-Azhar Mosque , romanized: al-Jāmiʿ al-ʾAzhar, lit. 'The Resplendent Congregational Mosque', Egyptian romanized: Gāmiʿ el-ʾazhar), known in Egypt simply as al-Azhar, is a mosque in Cairo, Egypt in the historic Islamic core of the city. Commissioned as the new capital of the Fatimid Caliphate in 970, it was the first mosque established in a city that eventually earned the nickname "the City of a Thousand Minarets".[b] Its name is usually thought to derive from az-Zahrāʾ (lit. 'the shining one'), a title given to Fatimah, the daughter of Muhammad. After its dedication in 972, and with the hiring by mosque authorities of 35 scholars in 989, the mosque slowly developed into what it is today.

The Mosque-Madrasa of Sultan Hasan is a monumental mosque and madrasa located in Salah al-Din Square in the historic district of Cairo, Egypt. It was built between 1356 and 1363 during the Bahri Mamluk period, commissioned by Sultan an-Nasir Hasan. The mosque was considered remarkable for its massive size and innovative architectural components, and is still considered one of the most impressive historic monuments in Cairo today. Sultan al-Nasir Hasan (full name: An-Nasir Badr ad-Din Hasan ibn Muhammad ibn Qalawun) ascended the throne at the age of 13 in 748 AH/1347 CE. When he reached maturity in 1350, he arrested the Emir Manjaq who controlled all of the state's affairs. Prior to that arrest, the emir was restricted to an allowance of just one hundred dirham per day. This pocket change was collected by servants for the Sultan. It's especially striking considering that during that time, the emir Shaykhu was estimated to have an income of 200,000 dirham per day.

Al-Rifa'i Mosque , transliterated also as Al-Rifai, Al-Refai, Al-Refa'i, locally known as El-Refa'i, and in English: the Refaai Mosque) is located in Citadel Square, adjacent to the Cairo Citadel. Its name is derived from the Ali Abu Shubbak who is buried in the mosque. Now, it is also the royal mausoleum of Muhammad Ali's family. The building is located opposite the Mosque-Madrassa of Sultan Hassan, which dates from around 1361, and was architecturally conceived as a complement to the older structure as part of a vast campaign by the 19th century rulers of Egypt to both associate themselves with the perceived glory of earlier periods in Egypt's Islamic history and modernize the city. The original structure on the site was a small 12th century Fatimid-era mosque, known as the Al-Dakhirah Mosque.[2][3] But later, the grandson of Ahmad al-Rifa'i, Ali Abu Shubbak al-Rifa'i, was buried within it, and the place was converted into a Zawiya for the Rifa'i tariqah.
