The Yerebatan Samici (Basilica Cistern)
The Yerebatan Samici, or Basilica Cistern, is the largest of several hundred cisterns located beneath the city of Istanbul in Turkey. Built in the sixth-century during the reign of Byzantine Emperor Justinian I, it is located one hundred-fifty meters southwest of the Hagia Sophia and currently maintained as a tourist site.
Before the construction of the cistern, a public building serving as a commercial, legal and artistic center, called the Stoa Basilica, was located on the site of the large public square at the First Hill of Constantinople. After assuming control of the empire in 324 AD, the Emperor Constantine built the Basilica Cistern on that site. The cistern served as a water filtration system for the extensive palace complex of Constantinople
and other public buildings on the hill. After the Nika Riots of 532 destroyed nearly half of the city of Constantinople, the original cistern was rebuilt and enlarged during the reign of Emperor Justinian.
The Basilica Cistern/s chamber is about ninety-eight hundred square meters and is capable of holding eighty-thousand cubic meters of water. The ceiling, nine meters in height, is supported by twelve rows, spaced five meters apart, of twenty-eight marble columns, with capitals of mainly Corinthian and Ionic styles. The majority of the columns, carved and engraved from various types of marble and granite, were likely brought to Constantinople from other parts of the empire
Entrance to the Basilica Cistern is reached through a descent down fifty-two stone steps to the water storage. The source for the cistern’s water supply is the current Eğrikapı Water Distribution Center in the Belgrade Forest, located nineteen kilometers north of Istanbul. The water’s long journey
includes a one-thousand meter run through both the Valens and Mağlova Aqueducts to reach the storage basin of the cistern.
The Basilica Cistern has undergone several restorations since its foundation. During the eighteenth-century reign of Ottoman Emperor Ahmed III, architect Muhammad Agha of Kayseri oversaw a major restoration in 1723. A second major restoration during the nineteenth-century was conducted during the reign of Sultan Abdulhamid II. The Metropolitan Museum of Istanbul also undertook two repairs to cracks in the masonry and damage to the columns, the first in 1968 and the second in 1985.
During the 1985 restoration, fifty thousand tons of mud were removed from the Basilica Cistern, and platforms for tourists were built to replace the former tour boats. The cistern was opened to the public on the 9th of September in 1987. It has appeared as settings in fiction novels, video games, and films, including the 1063 James Bond “From Russia with Love” and Jean-Baptiste Andrea’s 2013 thriller “Brotherhood of Tears”
