Basilica Cistern, located in Istanbul, is a remarkable historical site offering insights into Byzantine architectural brilliance and engineering. Known as the largest surviving cistern in the world, it serves as a monument to the ingenuity of the Byzantine era.
Constructed in the 6th century by Byzantine Emperor Justinian I, the Basilica Cistern was primarily built to supply water to the Great Palace and surrounding areas. Following damage due to a fire, Justinian I restored and expanded the original cistern, incorporating advanced features such as a water purification system under each dome.
The cistern spans 140 meters by 70 meters, covering an area of 9,800 square meters. It features 336 columns arranged in 12 rows of 28, supporting the ceiling. This grandiose underground structure, once capable of holding enough water to sustain 100,000 people for a year, was aptly nicknamed „Yerebatan Sarayı“ or „Sunken Palace.“
After centuries of neglect, the Basilica Cistern was only used for garden watering during the Ottoman era, following Islamic law that discouraged the use of stagnant water. Restoration efforts in the 19th century and mid-20th century revived this architectural marvel, leading to its current status as a major tourist attraction.
The Basilica Cistern, also celebrated as the „Sunken Palace,“ showcases columns believed to have been sourced from ancient Roman buildings. It played a vital role in firefighting before falling into disrepair post-Ottoman conquest of Constantinople.
The Basilica Cistern is centrally located in Sultanahmet Square, opposite the majestic Hagia Sophia and near the Blue Mosque, just next to Topkapı Palace. You can easily walk here from the Grand Bazaar in about 20 minutes.
