Undoubtedly, a city that has hosted important empires like Istanbul had numerous enviable features. However, Constantinople city is one of the most sieged cities in history. For this reason, the city had some vital problems in proportion to its majesty. The most critical of these was the provision of water to the city. Prokopios (lived between 500-563 AD), the famous historian of the Byzantine era, said: “…. The sea forms a crown around the city. Istanbul is a city created and brought to life by the sea. ” Although Istanbul benefited from all the generosity of the sea, it was always a difficult problem to solve when it comes to supplying drinking water in the city built on rocks. The sieges sometimes took months or even years. There were not enough fresh water resources in the city. For this reason, Byzantines built huge cisterns as a solution. The number of cisterns in Istanbul is estimated to be around 200 today and approximately 1,000,000 cubic meters of water were provided.

This cistern met the water needs of the emperor’s palace, which occupied a large area, and other residents in the region, known as Sultanahmet during the Byzantine period. After the conquest of Istanbul, the gardens of Topkapı Palace also benefited from the water of this place.
