Cistern of the Greater King Issa

This cistern is located in al-Aqsa Mosque, between the western colonnade and the south-western colonnade, on the roof of the Holy Rock, but on the level of the floor of al-Aqsa Mosque. Al-Malik al-Matham Issa Ibn al-Adil al-Ayyoubi was the one who issued the order for building this cistern in the year 607 Hijri / 1210-1211 AD.

This cistern was constructed to collect and store water, to be used by the visitors of al-Aqsa Mosque.

Initially, its structure included three corridors with intersecting vaults. Lately, the Cistern stopped functioning, and a part of it is currently used as a medical clinic for al-Aqsa Mosque.
