Historic designs: Aden’s famed cisterns
There is no conclusive evidence as to when the tanks were built, estimates range from the first century AD to the 11th. However, historians do agree that the structures were an extraordinary architectural feat for the time designed to capture and store water for the city in their interlinked design.
Strategically positioned below Shamsan Mountain in order to capture runoff rain water from the mountain, the cisterns are no longer used to provide a water supply. Instead, they draw tourists—domestically and internationally—who come to appreciate the structures and this architectural feat.
