Cairo has many fortresses. The Citadel is the one that stayed in use. Built by Saladin between 1176 and 1183 on the Mokattam Hill east of the city, it served as the residence of the Ayyubid, Mamluk, Ottoman and Muhammad Ali dynasties for almost seven centuries. The British military occupied it from 1882 to 1946; the Egyptian army held it until 1983. Today it is open to the public as a heritage complex — a fortress that has not been a ruin for any continuous period since it was built.
Saladin and the foundation
Saladin chose the site for both strategic and symbolic reasons. The Mokattam Hill rises ninety metres above the floodplain of central Cairo; from its summit the city, the Nile and the western desert are all in view. The hill was already considered defensible — there were small Ayyubid garrison posts on it from the 1160s — but Saladin's decision was to fortify the entire ridge with a continuous curtain wall, twelve metres thick at the base, with twelve towers spaced along it. The work was completed under his nephew al-Kamil in the early 1200s.
The Mamluk period
Under the Mamluks (1250–1517), the Citadel became the de facto capital of Egypt. Sultans built audience halls, harem quarters, stables, garrison barracks and three mosques within the walls. Most of the Mamluk-era buildings were demolished by Muhammad Ali in the early nineteenth century to clear the ground for his own mosque and palace; what survives of the Mamluk Citadel is fragmentary but powerful — sections of the original curtain wall, the gate of al-Mudarraj, the foundations of the audience halls.
The Mosque of al-Nasir Muhammad
The earliest surviving mosque in the complex, dating from 1318. Built by the third reign of Sultan al-Nasir Muhammad; the mosque carries the distinctive pencil-thin Mamluk minarets and an interior of bare stone — a deliberate Mamluk preference for restraint over ornament. The mihrab is undecorated except for the original cut-stone surround. The mosque is closed during Friday prayers but otherwise open.
Muhammad Ali and the alabaster mosque
Muhammad Ali Pasha (r. 1805–1848) is the founder of modern Egypt. He massacred the remaining Mamluk amirs in the Citadel courtyard in 1811, demolished most of their buildings, and built his own residential palace and the mosque that dominates the modern Citadel skyline. The Mosque of Muhammad Ali was begun in 1830 and completed in 1848, the year of his death. The architect was the Greek Yusuf Bushnaq, and the design follows the late Ottoman style of Istanbul — two domes over a central court, two pencil minarets, an interior alabaster facing that gives the mosque its English name.
The mosque interior is best experienced in mid-afternoon. The high windows above the central dome admit a band of golden light that drops onto the alabaster floor. The clock in the western courtyard was a gift from King Louis Philippe of France in exchange for the obelisk of Luxor that now stands in the Place de la Concorde — a swap that, on the assessment of any honest art historian, was not in Egypt's favour. The clock has never worked properly.
The clock in the courtyard never worked. The obelisk it was traded for still stands in Paris.
The three on-site museums
The Military Museum
The largest of the three, housed in the former Haram (royal harem) palace. Twenty-three rooms covering Egyptian military history from the pharaonic period to the present, with a strong emphasis on the 1973 October War. The presentation is patriotic and detailed; visitors interested in modern Egyptian history find the rooms covering the period 1948–1973 the most substantive.
The Royal Carriages Museum
Eight historic state carriages from the courts of Khedive Ismail and the Egyptian royal family up to 1952. Reopened in 2020 after a long restoration. The principal exhibit is the gold-painted state carriage of Khedive Ismail, used at the opening of the Suez Canal in 1869.
The Police Museum
The smallest and oddest of the three. Three rooms on the history of policing in Egypt, with selected uniforms, weapons and case files. The most interesting room concerns the criminal trials of the early twentieth century.
The Western Terrace
From the open ledge to the west of the Muhammad Ali mosque, the panorama runs over all of Cairo. On a clear day — and clear days in Cairo are rare but real, particularly after a winter rain — the three pyramids of Giza are visible on the western horizon, eighteen kilometres away. The pollution and dust haze of the modern city makes the view a question of weather more than of effort. Early morning, before nine, is the most reliable window.
Eight hundred years of continuous occupation. The fortress was never a ruin. It is the rarest condition for any old building.
Practicalities
- Open 09:00 – 17:00 daily.
- One general ticket admits the holder to all the on-site mosques and the three museums.
- Allow two and a half to three hours for a comprehensive visit; ninety minutes for the principal mosque and the western terrace alone.
- Modest dress required inside the mosques; scarves are available at the entrance but bringing one is advisable for ease.
- Closed shoes; the stone courts are uneven.
- The Citadel café offers shade and decent coffee; the upper terrace pavilion is the better choice for the view.
Approach
From central Cairo: fifteen to twenty minutes by taxi up the Mokattam approach roads (Salah Salem). The Citadel has its own dedicated parking. Public transport options exist but are slow; a taxi or rideshare is the standard. Combined Citadel + Mosque of Sultan Hassan + Refai Mosque + Khan el-Khalili is a comfortable full Cairo day.
