The cistern lying west of it was built in the late Mamluk (15th-16th century) and lay adjacent to the northern enclosure. With two rows of columns, it was larger and reached a capacity of almost 350 m?. When constructing the new gun platform, the Ottomans had to abandon this huge water reservoir, most probably with some regret. They filled it with rubble and shattered the small brick domes of its roof in order to level the terrain before constructing the artillery platform.
