General Information

The existence of this colossal underground structure is not known to all travelers hastily visiting Istanbul on their way to the Mediterranean Turkish resorts. Meanwhile, the Basilica Cistern is literally under the feet of tourists exploring the Ayia Sofia, the Blue Mosque, and other famous structures in the historic center of the city.

Fortunately the existence of a secret underground reservoir was not known to the Ottomans who captured and mercilessly destroyed the city of Constantine in 1453. It is very likely that the surviving defenders of Byzantium spent their last days here. Subsequently, the cistern was discovered and it supplied water to the palaces and gardens of the Turkish sultans before being abandoned and turned into a giant underground garbage dump. Only in 1985 the underground was cleaned up and turned into a tourist attraction. Today this monument of Byzantine architecture is under state protection. The Basilica cistern is included in the list of outstanding buildings of the cultural heritage of the Greco-Roman civilization that developed in Constantinople.

History of the underground cistern

In 20s of IV century on a hill in the center of Constantinople grandiose building has developed. A huge pit appeared in the market square. Basilevs Constantine Great has enjoined to create in capital of empire the huge underground reservoir intended for supply of palace constructions and hundreds thousand inhabitants of city. Chronicles tell us that 7 thousand builders worked here. A many kilometers long aqueduct that pumped water from the surrounding mountain springs was built for the strategic site. A part of this arched aqueduct made of sturdy Roman bricks still crisscrosses the streets in the center of today’s Istanbul. Two hundred years later, during the reign of Emperor Justinian I, the Basilica Cistern was fortified, enlarged and slightly rebuilt.

Greek historian Procopius of Caesarea who lived in the 6th century described in detail the Constantinople cistern in his treatise “On Buildings” which has survived to our time. Even then, the structure astonished by its scale and perfection of engineering technology.

Strangely enough, after the fall of Constantinople, the Turkish rulers of Istanbul for several decades knew nothing about this huge underground, although locals even caught fish there, and often threw in the sinkholes garbage. However, they believed that there was an underground lake under the streets of the city. Only two generations later, in the middle of the 16th century, the cistern was discovered by the traveler Pierre Gilles, who was guided by an ancient description of Procopius of Caesarea.

It is known that during the reign of the Ottoman sultans, the underground reservoir was repaired several times. The large-scale repair was carried out in 1723, by order of Sultan Ahmed III. Another reconstruction was carried out under Sultan Abdulhamid II, at the end of the XIX century.

In the mid 80’s of the last century, the city authorities of Istanbul decided to clean the Basilica Cistern. From the underground was extracted 50 thousand tons of dirt and debris, which had accumulated over the centuries. There were found artifacts which have filled up the Istanbul museums and also some skeletons of the people who have become victims of terrible crimes which have remained unpunished.

In May 1987 the ancient dungeon was opened to all comers. Berths for boats, which were used to take tourists, were built there.

Over the past thousand and a half years, nothing has changed in the dungeon. The mighty brick walls of the reservoir, 4 meters thick, were impregnated with a layer of waterproofing mixture based on resins. By the way, Byzantine waterproofing is reliable to this day, and the secret of the water-resistant mortar has not been revealed. Researchers believe that the builders hammered millions of chicken eggs into the lime mixture. The walls form a rectangular basin measuring 140 by 65 meters, outlining an area of 9,800 square meters. Up to 100 million liters of water could be stored here.

The sturdy vaults of the Basilica Cistern are built in the technique of multiple cross-shaped domes and arches, and are supported by a forest of marble and granite columns 9 meters high.

Curious travelers will want to examine the endless rows of 336 columns with capitals, executed in various classical Greek and Roman styles, indicating the different eras of their creation. Several pillars of Doric order with cannelures were carved for unknown monuments erected several hundred years before Christ.

The columns were taken here from ancient temples and structures destroyed on the orders of Christian bishops, triumphal arches glorifying ancient “wicked” rulers and heroes. In the northwest corner of the Basilica’s cisterns are the most famous of these – two columns with perfectly preserved relief images of the head of Medusa the Gorgon. Interestingly, the faces of Medusa are carved at an angle that excludes a direct look of the monster in the eyes of the audience, because according to legend this monster was capable of turning a man into a stone statue. According to architectural historians, the statues were removed from the facade of a public building from the late Roman period. Signposts will lead you to the Medusa.

Columns with the head of Medusa at the base

Several of the columns are engraved with stylized eyes and tears. Ancient chronicles claim that these signs were carved in memory of the many slaves who died during the grandiose construction.

The Basilica Cistern has now been turned into a museum. The columns are beautifully illuminated, there is soft instrumental music, you can hear the measured drops and murmuring of flowing water. In the glare of light between the columns swim fish, and on the marble bottom flicker coins, which by tradition are thrown into the water by tourists. Sometimes concerts and cultural events are held in this huge room with good acoustics.

The Basilica cistern in cinematography

The mysterious interiors of the Basilica Cistern, resembling a huge half-submerged cathedral, served as the perfect setting for episodes of many famous motion pictures. In 1963 here were filmed dramatic actions of one of the films about the adventures of Agent 007 James Bond – “From Russia with Love”, where the ancient reservoir is presented as a secret basement of the Soviet embassy in Turkey.

Mystical columns with the image of Medusa play the role of one of the keys of the message-puzzle in Dan Brown’s world bestseller “Inferno.” The Cistern was the setting for the film adaptation of this novel in the 2016 Hollywood blockbuster.

There are other man-made underground reservoirs from the ancient period available to tourists in Istanbul. One of them, the two-story Philoxenus Cistern (4th century), is located west of the Hippodrome, near the Constantine Forum, with its entrance located at 4 İmran Öktem Sokak Street. Its vaults are supported by 224 columns of marble and have interesting images on them.

In 2018, after being cleaned and restored, the Theodosius Cistern, built in the first half of the 5th century, was opened for viewing in the historic Fatih district. This small reservoir served only to supply water to the imperial palace and irrigate the gardens surrounding the royal residence.

According to archaeologists there are many more such structures in Istanbul, but their access is blocked by urban development and underground utilities.

The Basilica Cistern: An underground mystery in Istanbul

Basilica Cistern is one of the most mysterious buildings in Istanbul and a subject of increasing interest for inquisitive travelers. This underground structure, built over 15 centuries ago, is located near the city’s famous Sultanahmet Square. Once it served as the main reservoir of Constantinople. Today the ancient building is a museum with many noteworthy objects.

Basilica Cistern

The Basilica cistern goes deep about 12 meters. It can hold up to 80 thousand cubic meters of water. The walls of the structure are 4 meters thick, and a special mortar is applied to their surface, giving it water resistance. There are 336 columns, lined up in 12 rows, serving as the main support for the vaulted ceiling. The height of each of them is from 8 to 12 meters. Many researchers agree that the columns were not built specifically for the site, but were brought from other previously demolished ancient buildings.

From the photo of the Basilica Cistern in Istanbul, it is difficult to understand that this structure once served as a water reservoir: now the site looks more like an ancient temple than a water tank. That’s its mystique and tourist appeal. What you can see in the underground basilica and how to get there, we will consider in detail in our article.

A brief history

The construction of the Basilica cistern began back in the early 4th century during the reign of Emperor Constantine I. It was decided to erect the cistern on the site of the former Basilica of St. Sophia, which was destroyed by a major fire. That is why the cistern was given such a name. Some researchers believe that the construction involved at least 7000 slaves, many of whom died here. The construction of the tank was delayed for more than 200 years, and came to an end only in 532 during the reign of Emperor Justinian.

Basilica cistern without water.

It is worth understanding that the cistern was built in the ancient era, and engineers of the time had to implement an incredibly complex work to build a water pipeline several kilometers long. The water flowed from the Belgrade forest through the aqueduct of Valenta and entered the cistern through the pipes of the eastern wall. The Basilica tank could hold up to one hundred thousand tons of water: such volumes were needed in case of an unforeseen drought or a military blockade of the city.

The capitol of the column.

With the advent of the Ottoman conquerors in Istanbul in the 15th century, the cistern lost its importance. For a while its reserves were used to irrigate the gardens of Topkapi Palace, but soon by order of Suleiman the Magnificent a new water reservoir was built in the city, and the Basilica Cistern fell into disrepair and its existence was completely forgotten. In the following centuries, several European explorers rediscovered the ancient abandoned reservoir, but it did not arouse the slightest interest among the authorities in those years.

At the entrance to the Basilica Cistern

The value of the cistern as a historical monument was seen only in the 20th century. Then it was decided to carry out cleaning and restoration work inside its walls. Over hundreds of years tons of dirt accumulated in the cistern, so the restoration took quite a long time. As a result, the basilica was cleaned, its floors were concreted, and wooden coverings were installed on them for ease of movement. The official opening of the museum did not take place until 1987. Today in the Basilica Cistern in Istanbul you can also see water seeping out of the ground, but its level above the floor does not exceed half a meter.

What to see

First of all, it is worth noting the special atmosphere that reigns within the walls of the underground basilica. The subdued lighting and soft music, combined with the ancient architecture, create a kind of mystery and a feeling of being lost in the past. At the same time, the museum has its own attractions, which attract the most tourists.

Among the three hundred columns located in the cistern, one in particular stands out, dubbed the “weeping” one. Unlike the others, this column is decorated with patterns in the form of teardrops. In addition, it is always wet. These two factors are the reason for its name. Some believe that it was erected in memory of the slaves who gave their lives to build the reservoir.

Weeping Column

Interestingly, one of the ornaments has a small hole, which, according to local legend, can help make your dreams come true. To do this you just need to stick your thumb in the hole, turn it and make a wish.

Column with the head of Medusa at the base

Tourists are even more curious about the two columns mounted on blocks with the face of Medusa Gorgon: one of the heads lies on its side and the other is upside down. These sculptures are considered the brightest representatives of Roman architecture. It is still unknown how they got into the Cisterna Basilica, but one thing is clear: they were transferred here from another ancient building.

There are several theories about this unusual position of the Medusa sculptures. According to one version, the builders deliberately turned the head so that the mythical character, known for his ability to turn people into stone, would be deprived of this possibility. Another theory, quite the contrary of the first, asserts that in this way they wanted to show their disdain for Medusa Gorgon. Well and the third, most logical option suggests that this position of blocks simply more suitable in size for the installation of columns.
