History of the Basilica Cistern

The history of Basilica Cistern dates back to the 6th century. Built by Justinian, the most famous ruler of the Byzantine Empire, the cistern was one of Constantinople’s most important water resources.

The Historical Peninsula on which Constantinople was founded was a place known for its scarcity of water resources. Lack of water became a major problem as the city’s population grew.

A Roman Aqueduct was built in late antiquity to bring water to Constantinople from the mountains of Thrace. A part of these aqueducts built by Emperor Valens can still be seen in Istanbul.

Many cisterns were built in the city to store the water coming from this aqueduct. The largest of these was the Basilica Cistern, and it carried water to monumental structures such as Hagia Sophia and the Great Palace.

The Basilica Cistern takes its name from the Stoa Basilica, the public square under which it was built. The ceiling of the cistern is supported by 336 reused columns from the ancient Greek period. Cistern measuring 138 meters long and 65 meters wide. It covers nearly 1000 square meters.

1. Byzantine Cisterns in Istanbul

Most of the Byzantine cisterns in Istanbul are found in and around Sultanahmet. Theodosius Cistern, Cistern of Philoxenos and Basilica Cistern can be visited as museums. In addition, there is the Sarnic (Cistern) Restaurant and the Nakilbent Cistern located under a carpet store.

There are many articles on this website for those who want to trace the Byzantine heritage in Istanbul. For example, in this article you can find a list of the most important Byzantine buildings in Istanbul.

2. Rediscovery of the Cistern

It is hard to believe that such a distinctive structure could be forgotten for a long time. However, after the Ottomans conquered the city in 1453, the cistern was lost for a long time.

The Ottomans repaired the Valens Aqueduct and continued to bring water to the city through the Roman system. However, they did not use the cisterns. They connected the water pipes to the public fountains they built on the streets and provided water in this way.

For this reason, most of the Byzantine cisterns underground were forgotten. Byzantine historian Petrus Gyllius, who came to Ottoman Istanbul in the 16th century, made the rediscovery of the cistern.

3. Famous Movies Filmed in the Cistern

Unforgettable scenes of many famous movies were filmed in Basilica Cistern. The first production to film the Cistern was In 1963, From Russia With Love starring Sean Connery.

The final scene of the movie Inferno, based on Dan Brown’s novel, was also shot at Basilica Cistern. The famous actor Tom Hanks played the leading role of this movie, which was shot in 2016.

4. Medusa Heads in the Cistern

The Medusa Heads hidden in the farthest corner of the cistern will be the most interesting part of your visit. Since most of the columns in the cistern are taken from other structures, their lengths are different. For this reason, you will see stone blocks of various sizes under each.

The largest of these stone blocks are placed under the two short columns at the end of the cistern. The face of Medusa, a mythological creature, is engraved on these giant blocks, which cannot be noticed at first sight.

You will see that one of these Medusa Heads is placed sideways and the other is placed upside down. Many historians consider this to be due to the superstitions of Byzantine society.

Medusa has been a powerful figure since ancient times because it is a monster that turns people into stone. They didn’t want to face her, even if she was going to be submerged in a cistern.
