Skip the ticket office line and enter the Basilica Cistern. This cathedral-sized underground cistern was built in 532 AD during the reign of Emperor Justinian I to supply water to the Great Palace, storing up to 80,000 m³ of water delivered through a 20 km aqueduct from reservoirs near the Black Sea.

Go down 52 stone steps to reach the cistern, surrounded by 4-meter-thick firebrick walls. Walk through the forest of marble columns and see the famous Medusa heads up close. You can also learn how water flowed here from the Eğrikapı water distribution center in the Belgrad Forest via the 971-meter Valens Aqueduct and the 115-meter Mağlova Aqueduct.

The audio guide option is available in 25 languages, including Korean, so you can explore at your own pace. The guided tour option runs daily except Fridays at 10:30 AM and 4:30 PM, with a professional local guide sharing the stories, legends and architectural details of the cistern.
※ The Basilica Cistern is open daily from 09:00 to 18:00.
※ The security check cannot be skipped with the ticket, so waiting times may be longer at busy times.
