The Aqueduct of old Cairo, “Magra Al Ayoun" is a major medieval water work in old Cairo. one of the most prominent historical Islamic monuments in Cairo, because of its historical and geographical value since its establishment during the reign of Sultan Nasser Saladin, the founder of the Ayyubed state in Egypt who took power from 565 Ah / 1169 AD to 589 Ah / 1193 AD. It was neglected over the past 100 years by Egypt's rulers. Consequently, the aqueduct was exposed to natural deterioration and human encroachments. The valorization of the Aqueduct could greatly contribute to the enhancement of the old city fabric.
