What is the Basilica Cistern in Istanbul?
The Basilica Cistern was constructed during the reign of Byzantine Emperor Justinian I (527–565) to supply water to the Great Palace, the imperial residence, and surrounding public buildings. An earlier cistern had existed on the same site during the time of Emperor Constantine I, but it was severely damaged by a major fire.
Following this destruction, Justinian I ordered the reconstruction and expansion of the cistern, resulting in the structure that survives today. Water was transported to the cistern through the Bozdoğan (Valens) Aqueduct and a network of additional aqueducts extending from the Belgrade Forest.
Measuring approximately 140 by 70 meters and covering an area of 9,800 square meters, the Basilica Cistern is supported by 336 marble columns arranged in 12 rows of 28 columns each. With an estimated water storage capacity of nearly 100,000 tons, the vast and column-filled interior created a palace-like appearance, leading to its historical name, “Yerebatan Palace”.

Contemporary art and light exhibitions occasionally transform the space, blending ancient architecture with modern expression.
