Basilica Cistern Istanbul's Mysterious Underground Treasure

Hidden beneath the bustling streets of Istanbul’s historic Sultanahmet district lies the Basilica Cistern, one of the city’s most fascinating and atmospheric landmarks. Known in Turkish as Yerebatan Sarnıcı (Sunken Palace), this ancient underground water reservoir is a masterpiece of Byzantine engineering and a must-visit destination for anyone exploring Istanbul. With its dimly lit corridors, towering columns, and mysterious ambiance, the Basilica Cistern offers a unique journey into the past.

The History of the Basilica Cistern

The Basilica Cistern was built in 532 AD during the reign of the Byzantine Emperor Justinian I. It was constructed to meet the water needs of the Great Palace and other buildings in the area. The cistern was built on the site of an earlier basilica, which is why it is called the “Basilica Cistern.” It is the largest of hundreds of ancient cisterns that lie beneath Istanbul.

The cistern was forgotten for centuries after the Ottoman conquest of Constantinople (Istanbul) and was rediscovered in 1545 by the French traveler Petrus Gyllius. Since then, it has been restored and opened to the public as a historical site.

Architectural Features

The Basilica Cistern is an architectural marvel, showcasing the ingenuity of Byzantine engineering. Here are some of its most striking features:

1- Size and Capacity: The cistern measures 140 meters in length and 70 meters in width, covering an area of 9,800 square meters. It can hold up to 80,000 cubic meters of water.

2. Columns: The cistern is supported by 336 marble columns, each standing 9 meters tall. These columns were recycled from earlier Roman structures, giving the cistern a unique and eclectic appearance.

3. Medusa Heads: Two of the columns feature sculpted Medusa heads as their bases. One is placed sideways, and the other is upside down. The origin and purpose of these heads remain a mystery, adding to the cistern’s enigmatic charm.

4. Atmosphere: The dim lighting, reflective water, and echoing sounds create a mystical and almost otherworldly atmosphere, making it a favorite spot for photographers and history enthusiasts.

 Verified The highlight of our days in Greece and Turkey!
KSG tours was the highlight of our entire vacation. We spent a whole day with Kagan and Illayda who showed us all the wonderful sights of Istanbul: the Hipperdrome, the Blue Mosque, Hagai Sophia, the Grand Bazaar and the Spice Market. Kagan never tired of explaining the history of Istabul. He is so knowledgeable. And he was patient as we shopped. Illiayda picked us up from the airport late at night and returned up to the airport in the wee hours of the morning...all with a smile on her face. I felt like we had made new friends and look forward to returning one day. If you want to get a true live of Istanbul call KSG tours.

 Verified Book KSG tours. They do it right!
We had two wonderful days with Lale. The first day was cultural with a wonderful lunch spot she chose. There were four of us and she was so warm and informative. The second day was spent at the Grand Bazaar shopping and meeting local shop owners. Then the spice market and a wonderful Turkish bath and massage. I dealt with Kagan to book the trip and he was so communicative and excellent with details and follow up. They are the best!

 Verified Best days in Istanbul with the lady in the hat
We have just finished the most incredible three days in Istanbul with Lale. She was incredible. We were 2 families with 6 boys (19-29) she was soooo good she kept them interested, engaged. We are leaving Istanbul rich in knowledge about the culture, the food, the history, the people. She took us the perfect spots, the greatest restaurants and we really took advantage of every moment in Istanbul thanks to her. Her travel group KSG organized our transportation, a trip to Ephesus with a guide which was also incredible. I feel we got the best of the best everywhere, They were very prompt, very organized, very reliable. I would definitely recommend them eyes closed for any of your needs in Turkey. They are extremely knowledgeable and will guide you in the right direction. Even the Hammam we choose was perfect thanks to their recommendation. Thank you Lale and Kagan. Hope to see you again soon.

 Verified Perfect Day in Istanbul
Many family friends have used Kagan and KSG Tours over the years, so while in Istanbul on a cruise stop with my wife and two daughters we looked no where else. If you are going to be in Turkey, do yourself a favor and let Kagan and his wife, Lale, take care of all the details. Lale picked us up promptly at the port and handled all transportation. We were able to experience the Hippodrome, Blue Mosque, Hagia Sophia, Basilica Cisterns, carpet demo, Grand Bazaar and Spice Market. Because of Lale we did not wait in a single line and got to see and do far more than we could have on our own. If coming to Turkey, do yourself a favor and use KSG Tours!

 Verified Wonderful day tour of Istanbul with Lale/KSG Tours! Thanks!
My wife and I were on an 11 day Celebrity cruise with an overnight stop in Istanbul. We made a great decision to hire a private tour company, rather than go through a cruise line tour. We found Lale and Kagan Kosagan through a recommendation in a Rick Steve’s book. I contacted Kagan directly, and he was able to set me up with a day tour of Istanbul with his wife Lale. Lale was awesome! She was able to set up a beautiful day in touring old historic Istanbul that exceeded our expectations. We were able to visit many main sites including the spiritual Hagia Sophia, the Blue Mosque, Topkaki Palace, the Grand Bazaar, and spice markets. Lale provided us with important information about the history of Istanbul and Turkey. Her knowledge and delivery of the information was unmatched with any other tour experience we’ve had before. We had a great lunch at the Pudding Shop. She also helped my wife with some great shopping finds. Perfect! We would love to use the services provided by Lale and Kagan again on our next journey to Istanbul! Thanks Lale!

 Verified Türkiye - History, Cuisine, the Arts and More!
Lale and Kagan are amazing! My friend and I got their names from a recommendation in a Rick Steves guide book, and they didn’t disappoint! Kagan’s communication is top notch, and Lale’s knowledge, enthusiasm, and energy are unparalleled. Together, their commitment to delivering experiences tailored to their clients, and their love of their country, make for a magical and unforgettable trip. In fact, we were so delighted with our adventures, and with the hospitality we experienced in Türkiye, that we made a second trip within two years. Lale says, “We put a taste of honey in your mouth so that you hunger to return!” Trust them. They are the best!

 Verified Turkiye 's BEST TOUR COMPANY
My friend Jhan and I have worked with KSG Tours twice now. I cannot recommend them enough! This company was the BEST at every part of our tour, BOTH times. They provide a rich, incredible experience at every point! They are exceedingly honest, you get amazing value for your money, VERY thorough, VERY prompt at keeping you informed about all trip details before and during your time in Turkiye. They ANTICIPATE your needs and wants at every point. We not only toured Istanbul a second time but, we went to Adiyaman and Mardin, Turkiye. We saw Gobekli Tepe and Nemrut. ( The weather actually prevented us from going to the top of Nemrut, but WOW did they give it their best shot. They take you to where the locals go so you get a real Turkish experience in food customs. Lale can tell you how to cook all the Turkish dishes you taste! Turkish food is my absolute fav now due to the culinary encounters I experienced with KSG Tours. We stayed in incredible ,historical hotels . Lale and Khan are a complete delight to work with and get to know. Seriously , you will be thrilled with this tour group.

 Verified Walking Day Tour of Sultanahmet
Lale Kosagan took my wife and me for a fabulous private walking overview of the Sultanahment area of Istanbul. We walked and walked, 17,000 steps? I had been to Istanbul before, but it was new for my wife, so this was an excellent way to get a quick overview of the main tourist sites for a first time visitor. Late was patient and explained what we saw and provided the historic context. Highly recommended!!
