Restoring the Historic Basilica Cistern

• The Basilica Cistern was constructed in the 6th century during the reign of the Byzantine Emperor Justinian I.
• It was built to provide water to the city of Istanbul, which was then known as Constantinople.
• The cistern covers an area of approximately 9,800 square meters and can hold up to 80,000 cubic meters of water.
• It is supported by 336 columns, most of which were salvaged from ruined buildings and are thought to have been brought from various parts of the Roman Empire.
• The cistern was forgotten for centuries and was rediscovered by chance in the 16th century when a Dutch traveler noticed locals retrieving water from a hole in their basement floor.
• During the Ottoman Empire, the cistern was used as a water storage facility for the Topkapi Palace and other buildings in the area.
• In 1985, the cistern was opened to the public as a tourist attraction and today it remains one of the most popular sights in Istanbul.
