An intricate, 1600-year-old network of underground tunnels, water channels, and burial chambers lies hidden beneath the Hagia Sophia Grand Mosque in Istanbul, Türkiye 🇹🇷 Parts of the subterranean network date back around 1600 years to early Byzantine and Roman engineering, predating parts of the current structure built by Emperor Justinian I between 532-537 AD. For generations, urban legends claimed these passages formed a massive underground city connecting Hagia Sophia directly to Basilica Cistern or Topkapı Palace. While physical links to water networks exist, researchers note that a sprawling, continuous subterranean city has not been scientifically verified. . . . A hidden world beneath one of the most iconic monuments in human history is gradually coming to light, as Türkiye moves forward with plans to open previously inaccessible underground sections of Hagia Sophia in Istanbul to the public. The announcement was made by Turkish Culture and Tourism Minister Mehmet Nuri Ersoy, who revealed that extensive restoration and archaeological investigations are uncovering previously unexplored areas beneath the historic monument. The underground structures, according to minister, are just as fascinating as the magnificent building above ground. Authorities are now considering allowing visitors to explore selected sections once the necessary conservation, security and safety measures have been completed. Since February 2025, approximately 3,000 tonnes of mud and debris have been removed from underground tunnels, chambers and vaulted spaces, allowing specialists to reach areas that had remained inaccessible for centuries. The investigations have revealed ancient tunnels, water channels, cellars and other architectural structures that provide valuable evidence about the history of Constantinople and its sophisticated underground infrastructure. Tunnels served vital technical roles, functioning as sophisticated rainwater drainage systems, water distribution channels and natural air-conditioning pathways that naturally cooled massive cathedral. One of most intriguing discoveries is a four-chamber underground burial structure, known as hypogeum, located in northeastern section of Hagia Sophia. Archaeological investigations have revealed that parts of this complex are older than the present building itself, potentially offering new insights into earlier structures that occupied the site. Researchers are also examining underground systems that were used for rainwater drainage and water distribution, highlighting the remarkable engineering knowledge employed by ancient builders to protect the foundations of the monument. Built between 532-537 AD under Byzantine Emperor Justinian I, Hagia Sophia has survived nearly 1600 years of earthquakes, political upheavals, religious transformations and repeated historical changes. It originally served as the great cathedral of Constantinople before becoming an Ottoman imperial mosque following conquest of the city in 1453. It was later converted into a museum in 1934 and returned to mosque status in 2020. The current restoration project extends beyond the underground structures, with engineers also carrying out reinforcement work on the monument's dome and other architectural elements. Turkish authorities say underground areas will first be presented to journalists, while plans for public access will depend on the results of scientific assessments and the completion of necessary safety measures. For archaeologists and historians, discoveries offer a rare opportunity to investigate the hidden architectural layers of Hagia Sophia and better understand the engineering achievements of the Byzantine world. What lies beneath the ancient monument may still hold important clues about the earlier history of Constantinople, making the possibility of opening these forgotten spaces to visitors one of the most fascinating developments in the ongoing restoration of Hagia Sophia. #archaeohistories
