Basilica Cistern in Istanbul

A quiet, mysterious world beneath the streets of Istanbul.

Step Into the Underground Palace

Right across from Hagia Sophia, there’s a small doorway that many people walk past without noticing. But go down the steps, and you’ll find yourself in a completely different world—dark, cool, and full of history. Welcome to the Basilica Cistern, also known as the Sunken Palace.

Built in the 6th century by the Byzantine Emperor Justinian, this huge underground space once stored water for the palace and nearby buildings. Today, it’s one of Istanbul’s most unforgettable sights.

What to Look For in Basilica Cistern

336 Stone Columns: As you walk on the wooden paths over shallow water, you’ll see row after row of tall columns—many taken from older Roman buildings. Some have different designs and decorations, making every turn feel like a discovery.

The Medusa Heads: Deep in the cistern, two stone heads of Medusa lie under columns—one sideways, one upside down. Nobody knows exactly why. Some say they were placed like that to block her power.

The Weeping Column: One of the columns is always wet and has carvings that look like tears. It’s said to honor the workers who died during the construction.

📍 Location: Just across from Hagia Sophia, near Sultanahmet Square.

Location Details

Basilica Cistern

Alemdar, Yerebatan Cd. 1/3, 34110 Fatih/İstanbul

Basilica Cistern is one of the city’s most fascinating historical sites. Built in the 6th century during the reign of Emperor Justinian, this vast underground reservoir once supplied water to the Great Palace of Constantinople. Its dimly lit columns, silent waters, and famous Medusa head carvings create an almost otherworldly atmosphere. Over the centuries, it was forgotten, rediscovered, and restored, now standing as a quiet reminder of the city's layered past. Today, visitors walk on raised platforms above the water, taking in the history and engineering that kept an ancient city running.
