Citadel of Quaitbay included a large prison made for the princes and the state-men whom the Sultan kept away from his favor.After the Ottoman Turks had conquered Egypt, even they cared for this unique Citadel. They used it for shelter, and stationed it with infantry, artillery, a company of drummers and trumpeters, masons and carpenters.When Muhammad Ali Pasha became the ruler of Egypt in 1805, he renovated the old Citadel, restoring and repairing its outer ramparts, and he provided the stronghold with the most modern weapons of the period.
