Basilica Cistern History: Unveiling the Depths

The Basilica Cistern, known as "Yerebatan Sarnıcı" in Turkish, is an ancient underground water storage facility located in Istanbul, Turkey. The history of Basilica Cistern took in existence during the reign of Byzantine Emperor Justinian I in the 6th century. The cistern was built to supply water to the Great Palace of Constantinople and nearby buildings, especially during sieges. Measuring approximately 138 meters long and 64 meters wide, it has a capacity of 80,000 cubic meters of water. 


The structure is supported by 336 marble columns, each 9 meters high, arranged in 12 rows of 28 columns.
