If you’ve traveled to Istanbul or have it on your travel list, visiting the Basilica Cistern is one of the most fascinating and mysterious experiences you shouldn’t miss and you need ticket entrance to visit this historical place. This ancient structure is a gateway to an underground world that has captivated tourists and history and architecture enthusiasts for years.
History and Historical Significance
The Basilica Cistern was constructed during the Byzantine Empire under Emperor Justinian I around 530 AD. The main purpose of this vast underground reservoir was to supply fresh water to the palaces, government buildings, and important structures of Constantinople (the old name of Istanbul), especially during sieges when access to water sources was limited.
This underground structure was built on the remains of an old basilica (a large public building with tall columns), hence the name “Basilica Cistern.” Water was sourced from distant forests and reservoirs and transported into the city through a complex network of channels.
Architecture and Structure

The cistern is approximately 90 meters long and 70 meters wide and can hold about 80,000 cubic meters of water. Its ceiling is supported by 336 marble columns standing 9 meters tall, arranged in 12 rows of 28 columns each. Each column features different styles, including Corinthian, Greek, and Roman designs, some adorned with carvings and artistic motifs.
One of the cistern’s most intriguing features is the presence of two columns with Medusa heads placed sideways and upside down. These marble heads are believed to be repurposed from earlier structures to strengthen the columns. Many mysteries surround the reason for their unique placement, always drawing visitors’ attention.
Visiting Experience

Stepping inside the Basilica Cistern is like entering a different world; soft lighting reflects off the water and columns, creating a mysterious and tranquil atmosphere. The gentle sound of dripping water adds to the magical blend of history and architecture.
Visitors walk on wooden platforms that allow them to get close to the columns and the Medusa heads. Touring this underground marvel offers a glimpse into the sophisticated engineering and architecture of over 1,500 years ago.
During some times of the year, the cistern hosts music and cultural performances, making the visit even more memorable.
