History of the Basilica Cistern
The history of Basilica Cistern dates back to the 6th century. Built by Justinian, the most famous ruler of the Byzantine Empire, the cistern was one of Constantinople’s most important water resources.
The Historical Peninsula on which Constantinople was founded was a place known for its scarcity of water resources. Lack of water became a major problem as the city’s population grew.
A Roman Aqueduct was built in late antiquity to bring water to Constantinople from the mountains of Thrace. A part of these aqueducts built by Emperor Valens can still be seen in Istanbul.
Many cisterns were built in the city to store the water coming from this aqueduct. The largest of these was the Basilica Cistern, and it carried water to monumental structures such as Hagia Sophia and the Great Palace.
The Basilica Cistern takes its name from the Stoa Basilica, the public square under which it was built. The ceiling of the cistern is supported by 336 reused columns from the ancient Greek period. Cistern measuring 138 meters long and 65 meters wide. It covers nearly 1000 square meters.
1. Byzantine Cisterns in Istanbul
Most of the Byzantine cisterns in Istanbul are found in and around Sultanahmet. Theodosius Cistern, Cistern of Philoxenos and Basilica Cistern can be visited as museums. In addition, there is the Sarnic (Cistern) Restaurant and the Nakilbent Cistern located under a carpet store.
There are many articles on this website for those who want to trace the Byzantine heritage in Istanbul. For example, in this article you can find a list of the most important Byzantine buildings in Istanbul.
2. Rediscovery of the Cistern
It is hard to believe that such a distinctive structure could be forgotten for a long time. However, after the Ottomans conquered the city in 1453, the cistern was lost for a long time.
The Ottomans repaired the Valens Aqueduct and continued to bring water to the city through the Roman system. However, they did not use the cisterns. They connected the water pipes to the public fountains they built on the streets and provided water in this way.
For this reason, most of the Byzantine cisterns underground were forgotten. Byzantine historian Petrus Gyllius, who came to Ottoman Istanbul in the 16th century, made the rediscovery of the cistern.
3. Famous Movies Filmed in the Cistern
Unforgettable scenes of many famous movies were filmed in Basilica Cistern. The first production to film the Cistern was In 1963, From Russia With Love starring Sean Connery.
The final scene of the movie Inferno, based on Dan Brown’s novel, was also shot at Basilica Cistern. The famous actor Tom Hanks played the leading role of this movie, which was shot in 2016.
4. Medusa Heads in the Cistern
The Medusa Heads hidden in the farthest corner of the cistern will be the most interesting part of your visit. Since most of the columns in the cistern are taken from other structures, their lengths are different. For this reason, you will see stone blocks of various sizes under each.
The largest of these stone blocks are placed under the two short columns at the end of the cistern. The face of Medusa, a mythological creature, is engraved on these giant blocks, which cannot be noticed at first sight.
You will see that one of these Medusa Heads is placed sideways and the other is placed upside down. Many historians consider this to be due to the superstitions of Byzantine society.
Medusa has been a powerful figure since ancient times because it is a monster that turns people into stone. They didn’t want to face her, even if she was going to be submerged in a cistern.

Hi! Thank you for your awesome post and amazing pictures. Although I’m not a fan of dark, damp, underground places I’ll try to visit the underground Basilica Cistern when i visit Istanbul soon – for the first time ever!
Serhat Engül says
Hi Zana, thank you for the great review. Let me know if you need any help when you visit Istanbul. Have a good day!
Sofia says
Hi Serhat,
Thanks for the wonderful summary. Want to know if it’s open for visit now.
Thanks
Sofia
Serhat Engül says
Hi Sofia, thanks for the feedback. Unfortunately it hasn’t been opened yet. It looks like the restoration will continue throughout this year. If there is a change, I will note it in the article.
Sofia says
Thanks Serhat,
I read somewhere that they opened it for visitor while restoration but wasn’t sure. Thanks for the info : )
Serhat Engül says
You are welcome. In fact, the Basilica Cistern has been under restoration since 2015. For a long time we were able to visit even though the renovation was going on. However, it was completely closed in 2020 due to Covid and never opened again. I was in Sultanahmet a few days ago and it was still closed. Have a nice trip!
Danae Gallardo says
Hi. Is it still closed? I’m planning to go to Istanbul in May and I wish I could visit the cistern.
Serhat Engül says
Unfortunately the Basilica Cistern is still closed. However, there are other Byzantine cisterns that can be visited as an alternative.
For example, Binbirdirek Cistern (Cistern of Philoxenos) is open to visitors every day except Sundays and the ticket price is 50 Turkish Liras.
Also, Serefiye Cistern (Theodosius Cistern) is open every day of the week and the ticket price is 100 Turkish Liras. This cistern can be visited every hour and there is a 10-minute light show.
Lacy Williams says
Does anyone know when the Bascilica Cistern will reopen?
Serhat Engül says
Hi Lacy, no official information has been given about when the Basilica Cistern will reopen. However, as it seems from the outside, the restoration has come to its final stage.
Ingrid says
We’ll be there mid July .. still crossing my fingers it will be open by then:-)
Serhat Engül says
Hello Ingrid. Yes, I hope it opens by then. But even if it doesn’t open, the Cistern of Philoxenos is a good alternative as one of the biggest cisterns from the Byzantine period.
JingJing says
Hi Serhat,
Your blog has so much valuable and detail information. It’s our go-to blog for planning our upcoming trip to Istanbul.
The Madusa head in the Cistern remain mysterious. Besides what you have described in your blog, is there any other “stories” about it that you could share ? I guess we are just very curious about it.
Thank you so much!
Serhat Engül says
Hi Jing, thank you very much for your feedback on the blog. Yes, there are many stories to be told about the Basilica Cistern. But of course, I haven’t told all of what I know here.
If I write everything on the website, there will be nothing left to tell my guests who join my private guided tours. : )
Katy says
Holy guacamole, 300? We visited during the renovation works and paid 60? 70?
Must be Turkey regretting turning Hagia Sophia into a mosque. All the money that used to come in from there now need to be made elsewhere.
Theodosius Cistern used to be free, now they want 350. It’s ridiculous. Not going this time then.
Serhat Engül says
Hi Katy, yes, the entrance fees of museums in Istanbul have become a bit expensive right now. However, the period you visited was probably before the pandemic and it should not be forgotten that the USD-TL rate was very different compared to this time.
Basilica Cistern was closed to visitors during the pandemic (2020-2022). If you came during the renovation period (2015-2020), 1 Dollar was approximately 6 Turkish Liras at that time. Now, 1 dollar is about 19 TL.
For this reason, it wouldn’t be surprising if the price tripled. However, the recent price increase in cistern tickets was a bit exaggerated in my personal opinion. I think around 200 Turkish Lira, which equates to about 10 Dollars, would have been a fair price.
Maybe they wanted to foresee inflation and get ahead of it and to find an optimum price for the 2023 tourist season. From that perspective, it seems logical.
Anthony Tumonis says
Are there currently any renovations/repairs being done at Basilica Cistern, the Blue Mosque and Hagia Sophia? The last time I visited Istanbul the Cistern was closed and the Blue Mosque was under renovations?
Serhat Engül says
Yes, the renovations of the Basilica Cistern and the Blue Mosque, which have been going on for many years, were completed this year. However, the second floor in Hagia Sophia is still closed for renovations.
Hina A says
Hi Serhat,
Thank you so much for your all work! This blog is so informative and it helped be prepare for our family trip to Istanbul.
I just wanted to inform you that I visited the Basilica Cistern today and the price is now 550 TL!!!
We still went and were lucky to also wittness a live concert (Not sure if that is the norm, but it provided a fantastic atmosphere).
Serhat Engül says
Hi Hina, first of all thanks for your words about the blog. In fact, as stated in the article, the entrance fee to the Basilica Cistern between 09:00 and 19:00 during the day is 350 Turkish Liras.
According to the new practice, they keep the cistern open until 22:00 during the summer months. However, those who enter between 19:00 and 22:00 pay 550 TL.
Tanja says

Serhat Engül says
Hi Tanja, thank you for your feedback on the blog. But unfortunately I don’t think there is any discount for foreigners at Basilica Cistern. I’m not 100% sure about this, so you can ask the staff at the ticket office at the entrance.
