This priority entry ticket lets you skip the ticket line at the Basilica Cistern (Yerebatan Sarnıcı), a Byzantine-era reservoir hidden beneath Istanbul's old town. In a vast underground space where soft lights play on the water, see 336 marble columns and the upside-down Medusa heads. With the digital audio guide app, explore at your own pace while hearing the history and stories of this structure that supplied water to Constantinople.

Skip the ticket line and enter the Basilica Cistern. This is not a guided tour but a ticket for direct entry, so you can visit at any time on your booked day and explore freely. The Basilica Cistern is a masterpiece of Byzantine engineering built to meet Constantinople's water needs.

The audio guide is provided through a separate app, and the link is also shown on the voucher you receive by email. It is available in English, German, Italian, Spanish, French, Russian and Turkish. Walk through the dark, vast space lit by soft lights as you learn the history and background behind the architecture.

Walk among 336 marble columns rising from the water and see the skill of the ancient builders. Among the columns is an upside-down Medusa head whose origin is wrapped in mystery and myth. Escape the bustle of the city and feel the calm of this cool, echoing underground space.

On certain dates, concerts are held inside the cistern from 7:30 PM to 10:00 PM, so depending on your visit time you may enjoy the ancient space with music.
※ From 6:30 PM to 7:30 PM, the cistern is closed to regular visitors for event preparation, and an additional ticket is required to enter during this time.
※ During peak season, there may be waits at the security check.
