🏛️ The Basilica Cistern

Explore Istanbul’s Subterranean Masterpiece

Built in the 6th century during the reign of Emperor Justinian I, the Basilica Cistern (Yerebatan Sarnıcı) is a hauntingly beautiful world hidden beneath the streets of Sultanahmet. It is a place where engineering meets mystery.

⏳ A Timeless Underground Wonder

This ancient reservoir spans 9,800 square meters and was once the primary water source for the Great Palace of Constantinople.

• The Forest of Columns 🏛️: Support is provided by 336 marble columns, each 9 meters tall, recycled from ancient temples.
• The Gaze of Medusa 🐍: Hidden in the far corner are the two legendary Medusa Heads. Used as column bases—one sideways and one upside down—they remain the cistern's most enigmatic attraction.
• Atmospheric Waters 💧: Soft orange lighting and shallow water create a mirror-like surface, reflecting the grand arches above.

🐍 The Mystery of Medusa
