What Makes the Basilica Cistern Worth Visiting?
If there is one place in Istanbul you absolutely cannot miss, it’s the Basilica Cistern (Yerebatan Sarnıcı).
Stepping inside feels like walking onto the set of a fantasy movie. A vast forest of marble columns stretches into the darkness, while shimmering reflections dance across the water’s surface, creating an atmosphere that is both mysterious and enchanting.
For photographers, the changing light and reflections make this an especially memorable interior, subject to the venue’s current photography rules.
Purpose (Why Was It Built?)
- Builder: Constructed in the 6th century under Emperor Justinian I of the Eastern Roman Empire
- Function: A massive underground reservoir designed to supply drinking water to Istanbul’s Great Palace and surrounding buildings
- By storing water beneath the city, it ensured a stable water supply even during wars or droughts—an essential piece of ancient urban infrastructure.
Size
- Length: Approximately 140 meters
- Width: Approximately 70 meters
- Total area: About 9,800 square meters (roughly 1.5 times the size of a soccer field)
- Capacity: Estimated to hold up to 80,000 tons of water
Number of Columns
- Total: 336 columns
- Height: Each stands about 9 meters tall
- Design: A fascinating mix of column capitals—Corinthian, Doric, and Composite styles. Many were spolia, reused materials taken from earlier temples and monuments of the Roman and Greek world.

Highlights of Architecture and Interior
The Basilica Cistern is home to a selection of notable details and viewpoints, each filled with history, legend, and unforgettable charm:
1. Entrance Hall
As you descend the long staircase, you are suddenly confronted with a breathtaking sight—a vast hall filled with towering marble columns. The cool air and the faint shimmer of water set the mood. It feels like stepping into a palace buried beneath the earth, a world far removed from the bustling city above. From the very first moment, visitors are transported into an extraordinary, almost dreamlike atmosphere.
2. The Central Column Corridor
Stretching an impressive 140 meters in length, the central passage is lined with 336 marble columns, each nearly 9 meters high. The sight is nothing short of awe-inspiring. Many of these columns were repurposed from older Roman structures, which explains the fascinating variety of capitals—Corinthian, Doric, and even Composite styles. Look closely and you’ll notice the details that tell the story of ancient recycling in architecture. This is where the grandeur of Rome meets the practicality of Byzantine engineering.
3. The Visitor Walkway
The modern visitor walkway offers a striking view through the cistern’s rows of columns. Today, soft lighting illuminates the stone floor, which appears to float above the reflective waters. Walking along this path feels almost ceremonial, as if you have become part of Byzantine history itself. For many, it’s the most majestic stretch of the cistern.
4. The Weeping Column
Among the forest of columns, one stands out—the famous Weeping Column. Its surface is carved with tear-shaped patterns, sometimes linked in popular storytelling to the labor involved in building the cistern, although this interpretation is not securely documented. The symbolism is powerful, and visitors often pause to examine its distinctive carved surface. It’s a moment where history’s shadows feel very close.
5. Side Aisle Exhibition Area
The contemporary installations shown in these photographs create a striking contrast with the ancient stonework. Exhibitions may change over time.
6. Waterways and Reflection Points
One of the cistern’s magical features is the water visible across parts of its floor. The still surface acts like a mirror, reflecting the forest of columns to create an almost otherworldly scene. At quieter times of the day, the reflections become even clearer, perfect for the famous “upside-down architecture” photographs that fill Instagram feeds. Whether you are a professional photographer or just using your phone, this is one of the most rewarding places to capture the mystery of Istanbul.
7. Unique Column Capitals
A closer look at the capitals—the tops of the columns—reveals a striking diversity. Some are Corinthian, adorned with elegant acanthus leaves; others are Doric, plain and robust; while still others are Composite, blending different styles. This eclectic mix is the result of spolia—the ancient practice of reusing materials from older monuments. For architecture lovers, the cistern is a treasure trove, offering the rare chance to admire so many styles gathered in a single underground hall.
8. Northern Arch Structures
At the northern end of the cistern, massive arches and supporting walls showcase the brilliance of Byzantine engineering. These structures, designed to bear immense weight, are remarkably well-preserved. Standing beneath them, it is almost unbelievable to think that they have been holding steady for more than 1,500 years. Their endurance is a testament not only to the skill of the builders but also to the ingenuity of an empire that knew how to build for eternity.
9. The Upside-Down Medusa Head
One of the best-known highlights of the Basilica Cistern is the Upside-Down Medusa Head.
In Greek mythology, Medusa was the terrifying creature whose gaze could turn anyone into stone. So why is such a fearsome image placed here, as the base of a column in an underground water reservoir?
Several interpretations are often suggested, but the original reason for the heads’ placement is uncertain:
- Magical protection – Placing her face upside down may have been a ritual act to neutralize her deadly gaze.
- Practical purpose – The stone may simply have been reused in that position to adjust the column’s height.
- Symbolic meaning – Positioning a pagan idol upside down could represent the triumph of Christianity over ancient religions.
Whichever explanation you choose to believe, the Upside-Down Medusa continues to fascinate visitors. Even after 1,500 years, her silent, inverted gaze sends a strange shiver down the spine of those who pause to look—and almost everyone does.
10. The Sideways Medusa Head
Just nearby lies another treasure: the Sideways Medusa Head. Together with the upside-down version, these two sculptures appear more like works of art than mere building blocks.
The sideways face is especially intriguing because its expression seems to change with the light. As the exhibition lighting changes, shadows play across the features and can give the face a different expression.
Up close, the artistry is undeniable. The flowing hair and finely carved eyes reveal the detail of the ancient stone carving.
Visitors sometimes give the two Medusa heads symbolic meanings, but these modern interpretations should not be confused with documented Byzantine intentions. For this reason, the Medusa corner of the cistern is more than just a photo spot—it is a place where myth, history, and philosophy meet beneath the streets of Istanbul.

Barış“Exactly. That’s why if you come to Istanbul, this is one place you simply can’t miss.”
