History of the Basilica Cistern

The story begins in the Byzantine era. The Basilica Cistern was built to store fresh water for the Great Palace and nearby buildings. Water arrived by aqueduct and rested here in a huge vaulted chamber. The structure uses hundreds of reused columns from older sites, which is why designs and capitals vary. This layered look is part of the charm. If you want a broader timeline for context, save this overview of the best touristic places in istanbul to plan a full day nearby.

Who Built the Basilica Cistern?

The hall is quiet and cool, the light is gentle, and every footstep sounds like it belongs to another century.

Medusa’s Heads

The famous Medusa bases sit in a quiet corner. One is tilted. One rests upside down. They likely came from an older monument and were reused as strong blocks under short columns. Their position and role inspire stories. If you enjoy legends, read the short legend of basilica cistern and then study the faces with your own eyes. This is where many visitors take their favorite basilica cistern photos.

The Weeping Column

Look for a column with tear-like patterns. People say the carved drops honor workers who built the hall. Place your hand on the cool stone and notice how water changes the surface. Legends vary, but the feeling is the same. The space invites quiet reflection.

Reflective Waters

Water makes the architecture feel alive. Ripples turn columns into moving mirrors. If you want a clean shot, wait for the surface to settle. A slow breath helps. The stillness is part of the experience and one reason basilica cistern istanbul is beloved by travelers.

The Basilica Cistern and Its Legend

Stories give the hall a second life. Guides share short tales tied to heads, tears, and hidden meanings. You can enjoy them as folklore that adds a warm layer to stone and brick. For a fuller background, read this story of basilica cistern before or after your visit.

The Mystery of the Columns

Not all columns match and that is the point. Builders reused shafts and capitals from many sites, so you see a gallery of shapes. This makes the hall feel like a museum of forms set within water and light.

The Legend of the Medusa Head Columns

The heads appear powerful and calm at once. Some say the odd angles protect against bad luck. Others say it was simply practical engineering. Both can be true. That is how legends and stone live together in Istanbul.

Cisterns in general were spread everywhere in Istanbul during Byzantinian, these huge rooms were constructed to store water to be used later by people but the most important and largest one of them is Basilica Cistern.

Basilica Cistern was built by an order from Empire Justinian in 532 as a project of rebuilding the city after constantinople was destroyed by Nika riots, and historical fact say that it is the largest surviving cistern in Istanbul with 138 m in length and 65 m in width covering an area of almost one thousands meters and has the ability to store up to 80 thousands cubic meters of water which is considered a huge number at that time.

Basilica Cistern is the largest ancient underground cistern in Istanbul, which was used to store water in the past and is now a popular tourist attraction

The work and effort to build this cistern had to be incredible because the cistern has to be strong enough to hold the pressure of water inside of it. Thus, it was constructed with 336 marble columns supporting the structure lined up in 12 raws of 28 columns each measuring 9 m in height. Some say that these columns were recycled from older buildings in different parts of Byzantine empire or taken from what was left from construction parts of other buildings such as Hagia Sophia and you actually tell that when you see the the two heads of Medusa as the bases of the two columns, these heads were reused in the construction of Basilica cistern. It is still not known why the Emperor would give an order of recycling but some people suggest a reason for decreasing costs.

It is not for sure if the name Basilica is the original name of this cistern but it was given from the fact that it stands right under the area where the Roman Basilica once existed taking in consideration that Basilica means an open large place where business meetings and trade decisions were taken.

The Famous Subterranean Basilica Cistern In Istanbul

Despite that Basilica Cistern is very famous today and people from all over the world visit it everyday but it was not that famous long time ago, because sometime before the Ottoman Empire took over the city this cistern was shot down and closed and somehow it was forgotten by the government of the city until the early 1545 when a French scholar called Petrus Gyllius has discovered this masterpiece. Later on, the locals told him that they were able to get water from it by lowering buckets to their basement floors and some almost swore that they could catch fish from it. Petrus then was able to enter this cistern somehow passing from the basement floors of houses in the neighborhood. In any case, the Ottoman Empire authority did not pay attention to this discovery and the cistern turned out to be a trash dump but restored later to store water in it.

In 1980, some lightnings and decorations were added to the cistern to be used as a museum for tourists because it was not used anymore for water.

The Basilica Cistern was constructed in a very sophisticated way and was solving a very annoying problem for people at that time just like other cisterns. Today and after two thousand years of many wars and earthquakes, the Basilica Cistern still stands strongly as proof of how Byzantine Empire served its people and what kind of solutions it introduced to the world.

Once you enter this cistern, you will be amazed by its size, just imagine that the huge room you are walking between its columns and that can fit for more than two hundred people was once filled with water. In fact, you can still see some water left and you can still see fish swimming in it.

There is also a basilica in the cistern that gives the commonly used English name to the structure though traditionally, it is called ¨Yerebatan Sarnıcı¨ referring to its original function of underground water supply.
Basilica (Yerebatan) Cistern was used to reserve water for the Imperial Palace and neighborhood residences of Constantinople until its conquest by Fatih Sultan Mehmet. After 1453, it was used with this function for a short while and was left useless when the Ottoman architects built their own running water facilities around Topkapı Palace and Istanbul. It was a hidden mystery for Petrus Gyyllius, a Dutch traveler, who discovered the Underground Cistern in 1545 during his city walks. There were houses constructed on the cistern but fishmongers were selling a variety of fish caught in that hidden beauty. It had to wait until 1987 when Istanbul Municipality finished cleaning of this fascinating palace-like structure to open it as a so-called Yerebatan Museum.

Cisterns in Istanbul

Basilica Cistern

The Basilica Cistern, which Emperor Justinian built in 532, is also known as the Basilica Cistern because it is located under the Stoa Basilica. The cistern is a giant structure covering a rectangular area of 140 meters in length and 70 meters in width. There are 336 columns inside the cistern, each 9 meters high, which is descended by a 52-step stone staircase. These columns, erected at intervals of 4.80 meters from each other, form 28 rows of 12 each row.

These pillars rising in the water remind them of a vast forest and impress visitors as soon as they enter the cistern. The ceiling weight of the cistern was transferred to the columns by means of round cruciform vaults and arches. Most of the columns, most of which are understood to have been collected from older structures and carved from the granite of various types of marble, consist of one piece, and some of them are two pieces on top of each other. 

The headings of these columns have different features from place to place. While 98 of them reflect the Corinthian style, some reflect the Doric style. The brick-built, 4.80-meter-thick walls and brick-tiled floor of the cistern were plastered with a thick layer of Horasan mortar and made watertight. This cistern, which has 9,800 square meters, has a water storage capacity of approximately 100 thousand tons.

The two Medusa heads used as pedestals under the two columns in the northwest corner of the cistern are among the masterpieces of Roman sculpture art. Although there is no certain information about which building these heads from the 19th century were brought here, it is thought that they were brought here after being dismantled from an ancient structure belonging to the Young Roman Age. Those who came to visit the cistern watched in amazement.
