Descend a narrow stone stairwell and the noise of Sultanahmet vanishes. Below you: a forest of 336 marble columns rising from still, torch-lit water, the “Sunken Palace” that once supplied the Great Palace of Constantinople.

- Find the two sideways-carved Medusa heads at the cistern's far corner

Frequently Asked Questions
Why are the Medusa heads placed sideways and upside down?
Historians believe the orientation was chosen simply to fit the column height correctly, though legend prefers to say it neutralized Medusa's gaze.
How long does a visit to the Basilica Cistern take?
Most visitors are through in 30 to 45 minutes, making it an easy add-on to a Hagia Sophia or Topkapi Palace visit.
Is the Basilica Cistern accessible for strollers or wheelchairs?
The main boardwalk is flat and wheelchair friendly, though the entrance stairwell can be tight during peak hours.
