Basilica Cistern

The Basilica Cistern is one of Istanbul’s most atmospheric spots—a vast, ancient underground reservoir built in the 6th century. It’s best known for its forest of marble columns, the serene reflections in the water, and, of course, the mysterious Medusa heads hidden at the far end.

Depending on the ticket you choose, an expert guide will accompany you through the cistern. You’ll get the backstory behind the Medusa heads, learn how this shadowy space once supplied water to emperors, and hear quirky details you’d probably miss on your own.

Prefer to explore at your own pace? You can use the included audio app, available in five languages, to guide you through the cistern. If you want to see more of Istanbul, upgrade your ticket to include a guided tour of Hagia Sophia, an architectural masterpiece known for its massive dome and golden mosaics.
