Getting there by public transport
Located in Sultanahmet, the cistern is easy to reach from anywhere in the city:
- By Tram (T1 Line): Ride to Sultanahmet, then walk 3–5 minutes following signs for Yerebatan Sarnıcı.
- From Istanbul Airport: Take the Havaist shuttle to Sultanahmet, or the M11 metro to Gayrettepe and transfer to the T1 Tram at Kabataş.
- From Sabiha Gökçen Airport: Havabus to Taksim → F1 Funicular to Kabataş → T1 Tram to Sultanahmet.
- By Ferry (Asian side): Kadıköy or Üsküdar to Eminönü, then transfer to the T1 Tram.
- On Foot: A short walk from Hagia Sophia if you're already exploring Sultanahmet.
Tips for a better visit
Go early morning or late afternoon to dodge crowds. Wear comfortable, grippy shoes for the wet walkways, and bring a camera that handles low light well. Pair the visit with nearby Sultanahmet sights like Hagia Sophia and the Blue Mosque for a full day of exploring.
Rules to keep in mind
- Avoid flash photography — it disrupts the dim atmosphere.
- Tripods may be restricted at busy times.
- Walkways are elevated over water — watch your step.
- Large bags may not be permitted inside.
Visitor Experience
What you'll see inside
A forest of centuries-old Byzantine columns rises around you, dimly lit with the soft echo of dripping water setting a mysterious mood. Look closely at the two Medusa head column bases — one set sideways, one upside down — whose exact origin and reasoning still puzzle historians. Carp glide through the shallow water below, and the whole space offers a striking window into Byzantine engineering.
The wishing column
Near the back of the cistern, one column stands out for a damp hole worn into its surface. Local tradition says placing a finger inside and turning it a full circle grants a wish — a small, popular ritual among visitors.
A cool escape from the heat
Being underground, the cistern stays noticeably cooler than street level year-round — a welcome break on a hot Istanbul afternoon, and historically one reason locals used it as a refuge.
Best times to avoid crowds
- Early mornings: Beat the tour groups right after opening.
- Weekdays: Monday–Thursday is noticeably quieter than weekends.
- Off-season: Late autumn and winter see fewer tourists.
Tip: Avoid midday to early afternoon in spring/summer — book online or choose a guided tour with priority access to skip lines.
How long to plan for
Most visitors spend 30–60 minutes taking in the 336 columns, photographing the Medusa Heads and the Column of Tears, soaking in the ambiance, and reading the information panels. History or photography enthusiasts should budget the full hour.
You may recognize it from the big screen
The cistern's cinematic atmosphere has made it a filming location more than once — most famously the boat chase in the 1963 James Bond film From Russia with Love, and later a key scene in Inferno (2016), based on Dan Brown's novel. Locals also know the site by its Turkish nickname, Yerebatan Sarayı, or "Sunken Palace."
History & Significance
Why it was built
Constructed in the 6th century under Emperor Justinian I, the cistern sits beneath what was once the Stoa Basilica public square, chosen to supply the nearby Great Palace of Constantinople. Water arrived via aqueducts and tunnels from the Belgrade Forest.
Who built it
Byzantine engineers and laborers built the cistern under Justinian I's commission, drawing materials from across the empire. Its solid brick walls and arches still show their craftsmanship today.
What makes it architecturally unique
Each column was repurposed from older structures, so styles vary — Corinthian, Doric, Ionic — across the "forest" of supports. Combined with dim lighting and shallow water, the effect is both grand and eerie.
How it has survived so long
Thick brick walls sealed with horasan mortar have stayed waterproof for centuries, while a system of arches evenly distributes weight across the space. Ongoing maintenance keeps it intact for today's visitors.
