Basilica Cistern – The Story
Here are some note-worthy Basilica Cistern facts about the history and architecture of the cistern.
· History
The name of this subterranean Cistern is Basilica because it is situated under the First Hill of Constantinople, the Stoa Basilica, which currently serves as a public square. The Cistern was built between the 3rd and 4th centuries in the Early Roman Age as an artistic center. This was before the reconstruction was performed on the Cistern structure after a fire in 476.
The primary purpose for building the Cistern was to store water for the Great Palace during the Byzantine rule, which continued to provide a water supply to the Topkapi Palace after the Ottomans’ conquest in 1453.
Though the Cistern started being built in the 3rd century by Emperor Constantine, it was only enlarged and reached its current stature in 532. With the numerous historical texts found across history, it is claimed that 7,000 enslaved people were involved in the complete construction of Basilica Cistern.


· Architecture
Arranged in 12 rows and 38 columns, the cistern is built on 336 marble columns, each 30 feet high. The cistern has been salvaged through history and has reached its current grandeur as the most significant surviving Byzantine structure. The cistern covers a rectangular area of 9,800 square meters which is 140 meters long and 70 meters wide.
The structure can store up to 80,000 cubic meters of water where the water comes from the Eğrikapı Water Distribution Center in the Belgrade Forest. The Basilica descends through 52 stone steps into the central cistern, surrounded by a firebrick wall with a thickness of 13 feet.
Since its construction, the cistern has been subjected to numerous renovations and reconstructions, which hardly changed the structure but mainly focused on clearing the cistern from mud and other substances.
· Interior
Basilica Cistern is designed with a unique and elegant composition that gives a quiet and peaceful atmosphere. The columns of the cistern are made with the finest marbles, including the two famous attractions of the cistern – The medusa Heads.
The Medusa Heads are the two elegantly structured bases of the columns made with several types of marbles. The main reason for the Medusa Heads gaining popularity is that there is no history of their construction in the cistern. Most importantly, both the Medusa Heads are not upright, which raises more confusion about their presence under the columns.
