History of the Basilica Cistern

The Basilica Cistern was built in the 6th century during the reign of Byzantine Emperor Justinian I. Its purpose was to provide water for the Great Palace of Constantinople and other buildings in the area. The cistern was built using columns and other building materials taken from abandoned structures and pagan temples.
The cistern covers an area of approximately 9,800 square meters and can hold up to 100,000 tons of water. It was constructed using over 300 columns, each of which is approximately 9 meters tall. The columns are made of marble and are arranged in 12 rows of 28 columns each.
Over the centuries, the Basilica Cistern has played an important role in the history of Istanbul. During the Ottoman Empire, it was used as a water storage facility and was later used as a dumping ground for various waste materials. In the mid-20th century, the cistern was restored and opened to the public as a tourist attraction.
