Byzantine Cisterns in Istanbul
There are hundreds of Byzantine cisterns in the Old City of Istanbul. If you look carefully, you will notice that there are cisterns with red brick ceilings visible even in Hagia Sophia Square or the second courtyard of Topkapi Palace.
Istanbul, formerly known as Constantinople, had been under siege many times in history. The city, which had the most powerful city walls of the Middle Ages, succeeded in lifting the siege each time. In military history, these walls are called Theodosian Walls.
However, it was not only the walls that were necessary during the sieges. It was very important to meet the water needs of the city people. Therefore, there are numerous cisterns under the Historical Peninsula of Istanbul.
Today, three Byzantine cisterns are open to visitors as a museum in Sultanahmet. One is the famous Basilica Cistern (Yerebatan Sarnici), the other is the recently restored Theodosius Cistern (Serefiye Sarnici). Apart from these two, there is another cistern called Cistern of Philoxenos (Binbirdirek Sarnici).
History of The Basilica Cistern

The history of the Basilica Cistern goes back 1500 years, when the Byzantine Empire was at the height of its power. It was built in the 540s during the reign of the Byzantine emperor Justinian.
Justinian, who ruled the Byzantine Empire from 527 to 565, was also the ruler who built Hagia Sophia. He is considered the most important ruler of the Byzantine Empire, which survived for more than 1000 years.
The Basilica Cistern is really amazing in size. Built in 108 meters and 65 meters in size, the cistern is the largest cistern in Istanbul with an area of 9800 m2. The Cistern was built to meet the water needs of the Great Palace of Eastern Roman Emperors.
1. Ancient Columns of Basilica Cistern

Inside the cistern, there are 336 reused columns from various ancient Greco-Roman structures. When you look carefully at these columns, you will notice that they are not made for this cistern and are of different shapes and lengths.
Some of the ancient columns of the Basilica Cistern are from the ancient Greek period, while others are from the Roman period. The Byzantines, on the other hand, gathered columns from the ruins of these periods.
2. Medusa Heads in the Cistern

As you move towards the bottom of the cistern, you will see that large stones were placed under the two very short columns for support. Medusa’s face was engraved on these stones.
For the architects who built the cistern, the rocks of which medusa heads were engraved had no meaning. They told the workers to place the rocks under two columns shorter than the others. But in the 540s when the cistern was built, it had only been two centuries since Christianity had been accepted.
The figures of ancient Greek mythology still remained in the minds of people. The workers were afraid of Medusa, which turned everyone into stone. Therefore, they placed one of the Medusa heads on the side and one upside down.
3. Why is It Called Basilica Cistern?

There are various rumors about where the Basilica Cistern got its name. The most common of these is that the cistern was named as the Basilica Cistern because it was built under the square called Stoa Basilica, an important square during the Byzantine period.
Basilicas functioned as court buildings in the early Roman Empire. However, later, when Emperor Constantine accepted Christianity, they were converted into churches one by one.
The aim in doing this was to create a practical place of worship for the ever-increasing Christian community. Thus, for centuries, churches were inspired by the basilica plan.
