Cisterns of Istanbul (with addresses and sites). And other dungeons of Istanbul

Cisterns in Istanbul have been known since the time of Constantinople (now the city of Istanbul).

Since there were very few sources of fresh water in the city (Constantinople), the locals felt the need to collect and store fresh water.

For these purposes, the Byzantines built a system of aqueducts (aqueducts) and cisterns (reservoirs). Through aqueducts, water was delivered to cisterns, which were open and closed, and in which fresh water was stored.

The cisterns also differed in their designs. Some collected rainwater, while others were filled by the water supply systems laid to them.

There were a lot of such cistern reservoirs in the city. They were built under fortresses, palaces, rich houses and churches.

Today, some of the reservoirs have dried up, others have been destroyed or are in ruins, while others underground reservoirs have been converted into museums that can be visited and which are significant sights of the city.

Cisterns-museums in the center of Istanbul that you can visit

Basilica Cistern

The Basilica Cistern or Yerebatan Cistern (Yerebatan Sarnıcı) is one of the most famous, large and well-preserved underground reservoirs of Constantinople.

The cistern was built under the Byzantine Emperor Justinian I and was popularly called the "cistern-palace" because of the marble columns rising from the water, seemingly countless. The name "Basilica cistern" comes from the fact that there was a basilica at this place.

The cistern is a large underground structure that held about 100,000 tons of water and occupies a rectangular area equal to 140 meters in length and 70 meters in width. Inside the tank there are 336 columns with a height of 9 meters each, which form 12 rows of 28 columns each. Most of the columns were brought from ancient temples and old buildings, while others were carved from various types of marble. Therefore, the columns in the tank differ from each other.

One of the columns of the cistern is called the "Weeping column" or "Column of tears". It got this name due to the fact that, unlike other columns in the tank, it always remains wet, and there are patterns on its surface that resemble tear drops in shape.

The two Medusa heads used as pedestals under two columns in the northwest corner of the cistern are among the masterpieces of sculptural art of the Roman period.

Several legends are associated with these sculptures. According to one legend, paintings and sculptures of the Gorgon were used at that time to protect large structures and private premises, so the head of the Jellyfish was placed in a Cistern. According to another rumor, Medusa was a girl who was proud of her black eyes, long hair and beautiful body. Medusa loved Zeus' son Perseus. Meanwhile, Athena also loved Perseus and was jealous of Medusa. Therefore, Athena turned Medusa's hair into snakes, and all those who looked at Medusa turned into stone. Later Perseus cut off Medusa's head and used her power to defeat many enemies. Based on this, in Byzantium, the head of Medusa was engraved on the hilts of swords and placed upside down on the bases of columns so that the beholders would not be turned into stone.

The Basilica cistern has been captured in cinematography, including in the films "From Russia with Love", "Inferno" by Dan Brown, "The Invincible Sun" by V. Pelevin.

The Basilica Cistern is located in the historical center of Istanbul, not far from Blue Mosque and Hagia Sophia Mosque, at address: Alemdar, Yerebatan Cd. 1/3, 34110 Fatih/Istanbul, Turkey.

Theodosius Cistern

The Theodosius cistern or the Sherefiye cistern (Şerefiye Sarnıcı) is also one of the largest and most significant closed cisterns in the city, which has been restored today and functions as a museum, where visitors are shown a 10-minute show with three-dimensional effects and music.

It is assumed that the Sherefie cistern was built in 428-443, during the reign of Theodosius II. Water was delivered to the cistern from the aqueduct of Valens.

The cistern of Theodosius has the shape of a rectangle measuring approximately 45 × 25 meters and a ceiling height of 11 meters. It has 45 sail arches supported by 32 monolithic marble columns, girded with iron brackets and reaching a height of 9 meters. Read more about the Feodosiya cistern with photos...

Binbirdirek Cistern

The Binbirdirek Cistern (Binbirdirek sarnıcı), also known as the Philoxena Cistern (ΚινστρΡνα ΦιλονΝου), is the second largest reservoir in Istanbul after the Basilica Cistern.

From Turkish, the word "Binbirdirek" translates as "1001 columns", although in fact there are much fewer columns in the cistern.

The cistern was built during the reign of Constantine I (4th century). Over time, the cistern dried up, and was used as a workshop from the 16th century.

The cistern contains 212 of the 224 original columns. The area of the preserved cistern is 3584 square meters.

The columns in the cistern consist of two superimposed parts with truncated pyramidal capitals. It is known that the Greek letters engraved on the bodies of the columns are the signs of the masons who worked on the construction of the cistern and on the columns.

The Philoxene cistern is open to visitors as a museum. It is also used for exhibitions, concerts, banquets, weddings and other celebrations.

Entrance to the cistern is paid.
