In page Cairo Citadel:

"

This small domed building just outside the Citadel to the east was built in 1495-96 by an amir called Ya'qub Shah al-Mihmandar, a man originally from Erzincan (Turkey) who joined the Mamluk ranks under Sultan Qaytbay. Because of its dome, the building has the look of a mausoleum but it is actually a structure covering access to a cistern. It has an inscription that memorializes the victory of Sultan Qaytbay's army over Ottoman forces at Adana in a battle in 1486.[1] Today it is cut off from the Citadel and stands stranded between two highways (Salah Salem road and Kobri al-Ebageah) which pass right next to the Citadel on its eastern side.[2]
