Yerebatan Samici: Basilica Cistern

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”

May 29, 1453 marks the end of the Byzantine Empire with the fall of the city of Constantinople.

The Byzantine empire was the continuation of the Roman Empire in the East lasting into the Middle Ages. The capital of this empire was Constantinople, the site of ancient Byzantium. It survived the fall of the Western Roman Empire in the fifth century AD and continued to exist for an additional thousand years. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe.

The borders of the empire evolved significantly over its existence, as it went through several cycles of decline and recovery. During the reign of Emperor Maurice from 582-602 AD, the Empire’s eastern frontier was expanded and the north stabilized. However, his assassination caused the Byzantine-Sasanian War, which lasted from 602 to 628 AD, exhausted the empire’s resources, and contributed to major territorial losses during the seventh century. In a matter of years the empire lost its richest provinces, Egypt and Syria, to the Arabs.

The empire recovered again during the reigns of the Komnenian family; by the 12th century, Constantinople had become the largest and wealthiest European city. However, the city was delivered a mortal blow during the Fourth Christian Crusade. During this crusade, Constantinople was sacked in 1204 and the territories that the empire formerly governed were divided into competing Byzantine Greek and Latin realms. Despite the eventual recovery of Constantinople in 1261, the Byzantine Empire remained only one of several small rival states in the area. For the final two centuries of its existence, the empire’s remaining territories were progressively annexed by the Ottomans.

The capture of the capital of the Byzantine Empire by the invading Ottoman army occurred on May 29, 1453. The attackers were commanded by the then 21-year-old Sultan Mehmed II, who defeated an army commanded by Emperor Constantine XI Palaiologos and took control of the imperial capital, ending the seige of the city. After conquering the city, Sultan Mehmed transferred the capital of his Empire from Edime to Constantinople, and established his court there. The Hagia Sophia was converted into a mosque, the Greek Orthodox Church was allowed to remain intact, and Gennadius Scholarius was appointed the Patriarch of Constantinople.

The fall of Constantinople was a watershed moment in military history. The substantial fortifications of ramparts and city walls of the city had been a model followed by other cities throughout the Mediterranean region and Europe. The Ottomans ultimately prevailed due to the use of gunpowder which fueled their cannons.

On May 7, 558, the great dome of the Hagia Sophia in Constantinople completely collapsed.

Hagia Sophia is a cathedral located in Istanbul, Turkey. It is one of the greatest surviving examples of Byzantine architecture. The original cathedral was finished in 360 A.D., but due to a future of riots, rebellions, and the fall of empires, the structure was rebuilt multiple times, each version more grand than the last. Due to this rich history, the cathedral has crowned the bodies of both the Christian and the Muslim world.

The size and measurements of the Hagia Sophia are much larger than other religious buildings of its time. This structure is world renown for the colossal dome that sits over its central space. The dome is 56 meters from ground level, 32 meters from North to South and 31 meters from East to West. It was the largest pendentive dome in the world until the completion of Saint Peter’s Basilica in 1626, and has a much lower height than any other dome of such a great diameter.

Earthquakes in August 553 and December 557 caused cracks in the main dome and eastern half-dome. The main dome collapsed completely during a subsequent earthquake on May 7th in the year 558, destroying the altar steps, the altar, and the structural canopy over the altar. The collapse was due mainly to the unfeasibly high bearing load and to the enormous sheer load of the dome, which was too flat. These caused the deformation of the piers which sustained the dome.

Emperor Justian I ordered an immediate restoration. He entrusted it to Isidorus the Younger, nephew of Isidore of Miletus, who rebuilt with lighter materials than previously used and elevated the dome by another thirty feet– giving the building its current interior height. Moreover, Isidorus shaped the new cupola like a scalloped shell or the inside of an umbrella, with ribs that extend from the top down to the base. These ribs allow the weight of the dome to flow between the windows, down the pendentives, and ultimately to the foundation.

Hagia Sophia is famous for the light that reflects everywhere in the interior of the nave, giving the dome the appearance of hovering above. This effect was achieved by the insertion of forty windows around the base of the original structure. The insertion of the windows in the dome structure, beside letting more light enter, lessened its weight upon the underlying structure. This reconstruction of the Hagia Sophia dome, giving the church its present 6th-century form, was completed in 562. The rededication of the basilica presided over by Patriarch Eutychius occurred on December 23, 562.
