An Egyptian-French archaeological mission has revealed a remarkably sophisticated Mamluk-era water supply system, along with the remains of a mosque and centuries-old tombs near Cairo’s Salah Al-Din Citadel, offering a fascinating glimpse into how one of Egypt’s most important medieval landmarks functioned behind the scenes.
The discovery was made in the Arab al-Yasar and al-Hattaba districts as part of an ongoing project led by Egypt’s Supreme Council of Antiquities (SCA) and the French Institute for Oriental Archaeology (IFAO) to document and restore historic areas surrounding the Citadel.
A Sophisticated Water Network Beneath the Citadel
Archaeologists uncovered two massive stone wells measuring approximately 10 and eight metres deep. The wells were connected to a system of waterwheels that transported water uphill, helping supply the fortress and nearby communities.
Among the discoveries were animal pathways used to power the water-lifting mechanisms, stables, fodder storage areas, water basins, and stone-paved workspaces. Together, these elements paint a picture of a highly organized operation where people, animals, and machinery worked together to keep water flowing.
The Remains of a Historic Mosque
Alongside the water infrastructure, the mission uncovered the remains of a mosque that once served the surrounding community.
A burial chamber connected to the mosque was also found, as well as several tombs dating to different Islamic periods. One grave is believed to date back to the early Islamic era, suggesting the site remained active and significant for centuries.
Coins, Jewelry, and Everyday Objects from the Past
The team recovered ceramic qawadis, the vessels used in water-lifting systems, as well as coins dating to both the Mamluk and Ottoman periods. Archaeologists also uncovered jewelry, metal seals, additional coins, and fragments of weapons from the 18th and 19th centuries.
A New Chapter in the Citadel’s Story
According to Minister of Tourism and Antiquities Sherif Fathy, the discoveries represent a significant addition to our understanding of the Citadel and its evolution across different Islamic periods.
For centuries, the Citadel served as Egypt’s political and administrative heart, and every new discovery helps historians better understand how this iconic landmark operated on a day-to-day basis. The findings also support ongoing efforts to preserve Historic Cairo and strengthen its role as a cultural tourism destination.
From towering fortifications to hidden wells buried underground, Cairo continues to prove that its history runs deeper than we imagine. These newly uncovered structures reveal the ingenuity, organization, and daily rhythms that once powered life around the Citadel. As archaeologists continue their work, there’s no telling what other secrets may still be waiting beneath the streets of Historic Cairo.
