Byzantine Cisterns in Istanbul

There are hundreds of Byzantine cisterns in the Old City of Istanbul. If you look carefully, you will notice that there are cisterns with red brick ceilings visible even in Hagia Sophia Square or the second courtyard of Topkapi Palace.

Istanbul, formerly known as Constantinople, had been under siege many times in history. The city, which had the most powerful city walls of the Middle Ages, succeeded in lifting the siege each time. In military history, these walls are called Theodosian Walls.

However, it was not only the walls that were necessary during the sieges. It was very important to meet the water needs of the city people. Therefore, there are numerous cisterns under the Historical Peninsula of Istanbul.

Today, three Byzantine cisterns are open to visitors as a museum in Sultanahmet. One is the famous Basilica Cistern (Yerebatan Sarnici), the other is the recently restored Theodosius Cistern (Serefiye Sarnici). Apart from these two, there is another cistern called Cistern of Philoxenos (Binbirdirek Sarnici).

History of The Basilica Cistern

The history of the Basilica Cistern goes back 1500 years, when the Byzantine Empire was at the height of its power. It was built in the 540s during the reign of the Byzantine emperor Justinian.

Justinian, who ruled the Byzantine Empire from 527 to 565, was also the ruler who built Hagia Sophia. He is considered the most important ruler of the Byzantine Empire, which survived for more than 1000 years.

The Basilica Cistern is really amazing in size. Built in 108 meters and 65 meters in size, the cistern is the largest cistern in Istanbul with an area of ​​9800 m2. The Cistern was built to meet the water needs of the Great Palace of Eastern Roman Emperors.

Insider’s Note: The Cistern underwent a major restoration between 2015 and 2022, and now features striking contemporary art installations. However, please note that these artworks are not part of a permanent exhibition. For example, the elegant metal sculpture of a human figure that once floated gracefully above the water is no longer there. So if you’ve seen recent photos online, don’t be surprised if some of the artworks are missing or have changed during your visit!

1. Ancient Columns of Basilica Cistern

Inside the cistern, there are 336 reused columns from various ancient Greco-Roman structures. When you look carefully at these columns, you will notice that they are not made for this cistern and are of different shapes and lengths.

Some of the ancient columns of the Basilica Cistern are from the ancient Greek period, while others are from the Roman period. The Byzantines, on the other hand, gathered columns from the ruins of these periods.

2. Medusa Heads in the Cistern

As you move towards the bottom of the cistern, you will see that large stones were placed under the two very short columns for support. Medusa’s face was engraved on these stones.

For the architects who built the cistern, the rocks of which medusa heads were engraved had no meaning. They told the workers to place the rocks under two columns shorter than the others. But in the 540s when the cistern was built, it had only been two centuries since Christianity had been accepted.

The figures of ancient Greek mythology still remained in the minds of people. The workers were afraid of Medusa, which turned everyone into stone. Therefore, they placed one of the Medusa heads on the side and one upside down.

3. Why is It Called Basilica Cistern?

There are various rumors about where the Basilica Cistern got its name. The most common of these is that the cistern was named as the Basilica Cistern because it was built under the square called Stoa Basilica, an important square during the Byzantine period.

Basilicas functioned as court buildings in the early Roman Empire. However, later, when Emperor Constantine accepted Christianity, they were converted into churches one by one.

The aim in doing this was to create a practical place of worship for the ever-increasing Christian community. Thus, for centuries, churches were inspired by the basilica plan.

Insider’s Note: In the photo above, you see a visitor touching an ancient column and making a wish — a popular tradition for decades. Unfortunately, after the last major restoration in the 2020s, this iconic “Wishing Column” is no longer within reach of visitors. However, you can still admire its unique surface from about a meter away. With its distinctive motifs, it stands out from all the other columns in the cistern and continues to captivate the imagination.

Basilica Cistern Entrance Fee 2025

Basilica Cistern entrance fee is 1500 Turkish Lira as of August 2025. The standard ticket covers daytime access. Please note that Museum Pass Istanbul is not valid for this attraction. During the evening hours (Night Shift), the entrance fee increases to 2000 TL. This information was last updated on September 7, 2025.

The “Night Shift” ticket is slightly more expensive because, on some evenings, the Basilica Cistern hosts special events such as live music performances, contemporary art installations, or multimedia shows. While not every night includes such an experience, it’s a good idea to ask what’s happening on the evening you plan to visit. Even if there’s no event scheduled, exploring the cistern at night — when it’s quieter and less crowded — can be a good experience that some visitors find worth the extra cost.

Basilica Cistern is one of the most popular attractions in Istanbul, and waiting times can be long, especially during peak hours. These two fast-track ticket options offer a faster and more convenient entry with either an audio guide or a combo deal that includes Hagia Sophia.

Basilica Cistern Opening Hours 2025

In 2025, Basilica Cistern is open daily from 09:00 AM to 6:30 PM. Additionally, there is a special Night Shift session from 7:30 PM to 10:00 PM, which requires a separate ticket. This information was last updated on September 7, 2025.

The visiting hours of the museums in Istanbul may change due to renovations or events. Before you go, I suggest you check the museum’s official site one last time.

Insider’s Note: One of my guests once told me they had already visited the Basilica Cistern before our tour because someone recommended going in the evening. While this might sound appealing, it’s important to remember that the cistern is underground — it’s always dark inside, no matter what time you visit. If you’re considering the more expensive “Night Shift” ticket, make sure it’s for the right reasons: maybe there’s a special evening event like a concert or exhibition, maybe it’s your last chance to visit, or maybe you just prefer a quieter, crowd-free atmosphere.

How to Get to the Cistern?

The Basilica Cistern is located in Sultanahmet, the historical heart of Istanbul. You’ll find it just a stone’s throw away from Hagia Sophia, Blue Mosque, and Topkapi Palace — in fact, it’s tucked almost directly across from the entrance to Hagia Sophia. The entrance to the cistern sits at the beginning of Yerebatan Street, a short alley connecting Divan Yolu Avenue and Ayasofya Square. Just look for the small ticket booth and the modest crowd gathering near the steps descending underground.

If you’re walking around Sultanahmet, chances are you’re already just a few minutes away. The area is fully pedestrianized, and you can easily spot signs pointing to “Yerebatan Sarnıcı”, which is the Turkish name for the Basilica Cistern. If in doubt, just follow the stream of visitors flowing between Hagia Sophia and the tram station — they’re likely heading the same way.

To reach the cistern from Taksim Square, take the F1 Funicular from Taksim to Kabataş. From Kabataş station, transfer to Tram T1 heading toward Bağcılar, and get off at the Sultanahmet stop (about 15–20 minutes ride). From the tram station, it’s only a 3-minute walk to the Basilica Cistern. As you exit the tram, walk toward Hagia Sophia — the cistern will be on your left just before you reach the main square.

Conclusion

In the quiet depths beneath Istanbul’s bustling streets, the Basilica Cistern whispers stories of empires, mystery, and time itself. It’s not just a place you visit — it’s an experience that lingers long after you’ve climbed back to the surface.

After exploring this ancient underground world, take a moment to stroll through the serene courtyard of Hagia Sophia, just across the street. Or wander further into Gülhane Park, where sultans once walked, and enjoy a tea with a view of the Bosphorus.

If you’re curious to dive even deeper into the city’s hidden layers, consider visiting the Great Palace Mosaic Museum or the Archaeological Museums nearby — all within easy walking distance from the cistern.

And to round off your day, head toward Eminonu for some local street food, a bag of roasted chestnuts, or a boat ride along the Golden Horn. Because in Istanbul, history isn’t just behind glass — it flows around you like water under the stones.
