Basilica Cistern — Tickets, Tours & Visitor Guide
Step beneath Istanbul into a 6th-century Byzantine wonder. Built by Emperor Justinian I in 532 AD, the Basilica Cistern hides a forest of 336 ancient marble columns rising from still water, two enigmatic upside-down Medusa heads, and the legendary Crying Column — all dramatically lit, perfectly preserved, and just steps from Hagia Sophia.

What to See at the Basilica Cistern
Don’t miss these highlights during your visit.
The Medusa Heads
Two enormous Medusa heads serve as bases for columns in the northwest corner — one upside down, the other on its side. Their unusual orientation has spawned theories for centuries and they remain the cistern’s most iconic image.

The 336 Marble Columns
Twelve rows of 28 columns rise nine metres out of the still water, creating an otherworldly underground colonnade. Most are spolia — salvaged from older Roman buildings — with varied Corinthian, Doric, and Ionic capitals.
Know more →
The Crying Column
A single column carved with teardrop and peacock-eye patterns, said to weep for the roughly 7,000 enslaved labourers who died building the cistern. It really does glisten with moisture — touch it and feel for yourself.

Byzantine History
Built in 532 AD under Emperor Justinian I to supply water to the Great Palace of Constantinople, the cistern was forgotten and rediscovered in 1545 by a Dutch traveller who noticed locals fishing through their basements.
Know more →
The Cistern’s Carp
Carp have lived in the shallow waters since at least 1545, originally introduced to monitor water quality. Look toward the deeper walkway edges to spot them gliding silently between the column bases — a hit with kids.

Modern Art Installations
Following the 2022 restoration, the cistern hosts permanent and rotating contemporary works under the “Daha Derine” (Deeper Beneath) programme — sculptures emerging from the water, light, and immersive sound.
