Deep beneath the central Anatolian plains of modern-day Turkey lies one of the most remarkable and mysterious ancient engineering feats: the Derinkuyu Underground City. This vast subterranean city, located in the Cappadocia region, is a marvel of ancient architecture and ingenuity. It is the largest of several underground cities in Cappadocia, descending to depths of over 85 meters (280 feet) and able to house an estimated 20,000 people, along with their livestock, food stores, and belongings.
Derinkuyu has fascinated archaeologists, historians, and tourists alike since its discovery in the 1960s. With a rich history that spans thousands of years, it raises intriguing questions about who built it, how it was used, and what purpose it served. This article delves into the history, structure, and mysteries surrounding Derinkuyu, offering an in-depth look at one of the world’s most extraordinary ancient cities.
The Discovery of Derinkuyu Underground City
Derinkuyu remained hidden for centuries until its accidental discovery in 1963. A local resident in the town of Derinkuyu was renovating his home when he knocked down a wall in his basement and discovered a mysterious room beyond it. This led to the uncovering of a vast underground network of tunnels and chambers that extended deep into the earth.
Further exploration revealed that this was not merely a cave or storage area but a complex multi-level city designed to accommodate thousands of inhabitants. Archaeologists soon realized that Derinkuyu was part of a larger system of underground cities spread across the Cappadocia region.
The Structure of Derinkuyu: A Multi-Level Underground City
Derinkuyu is the largest and deepest underground city in Cappadocia, with 18 levels that descend more than 85 meters (approximately 280 feet) below the surface. The city is a labyrinth of interconnected tunnels, chambers, and passageways, with each level serving a specific purpose. The structure of the city reflects advanced planning and architectural sophistication, with features designed to meet the needs of a large population living underground for extended periods.
Key Features of Derinkuyu:
- Living Quarters: The city contained numerous living spaces, with each level providing rooms for families or groups to inhabit. These rooms were small but adequate, and they were often clustered around communal areas.
- Ventilation Shafts: One of the most impressive features of Derinkuyu is its system of ventilation shafts. These shafts allowed fresh air to circulate throughout the city, even at its deepest levels. Some shafts were also used as wells to provide fresh water from underground sources.
- Storage Areas: Derinkuyu was equipped with large storage rooms for food, wine, and other supplies. These storage areas were crucial for sustaining the population during extended periods underground.
- Animal Stables: The city had stables for livestock, including cows, goats, and sheep. The presence of stables suggests that the inhabitants intended to remain underground for extended periods and needed their animals for food, milk, and wool.
- Churches and Chapels: Several churches and chapels were found within the city, suggesting that the inhabitants practiced Christianity. The presence of religious structures indicates the importance of maintaining spiritual life while living underground.
- Schools and Meeting Halls: Archaeologists have discovered what appear to be schools and meeting halls within the city, suggesting that education and community gatherings were important aspects of life in Derinkuyu.
- Security Features: Derinkuyu was designed with defensive capabilities in mind. Large circular stone doors could be rolled into place to block passageways, preventing invaders from entering. These doors, which weighed up to 500 kilograms (1,100 pounds), could only be opened from the inside, making the city highly secure.
The History and Purpose of Derinkuyu
The exact origins of Derinkuyu Underground City are unclear, but it is believed that the first levels were constructed by the Phrygians, an ancient Indo-European people, as early as the 8th century BCE. Over the centuries, the city was expanded by successive civilizations, including the Persians, Byzantines, and early Christians.
Why Was Derinkuyu Built?
Derinkuyu was likely built as a refuge to protect its inhabitants from external threats. The Cappadocia region has a long history of invasions and conflicts, and its central location made it a crossroads for various empires and armies. Some of the reasons for constructing and using the underground city include:
- Protection from Invaders: The Cappadocia region was frequently invaded by various empires and tribes, including the Hittites, Persians, Romans, and Arabs. The underground cities provided a safe haven where the population could hide for extended periods, evading enemy forces.
- Religious Persecution: During the early days of Christianity, followers of the faith were often persecuted by both the Roman Empire and later by Muslim invaders. Early Christians are believed to have used Derinkuyu as a place of refuge, where they could practice their religion in secret and avoid persecution.
- Harsh Weather Conditions: The climate of central Turkey can be extreme, with very hot summers and cold winters. The underground city provided a stable, cool environment that was insulated from the heat and cold, allowing its inhabitants to live comfortably year-round.
- Survival During Sieges: During times of war or siege, the inhabitants of Derinkuyu could seal themselves off from the outside world, using the city’s food stores, water wells, and ventilation system to survive for months, if not years, without needing to emerge.
How Was Derinkuyu Built?
The construction of Derinkuyu required a combination of natural geology and human ingenuity. The volcanic rock that makes up much of the Cappadocia region is relatively soft and easy to carve, which allowed ancient builders to dig extensive tunnels and chambers with simple tools. However, creating a complex, multi-level city required careful planning and engineering to prevent collapses and to ensure adequate ventilation and freshwater supply.
It is believed that each successive level of the city was built over many centuries, with new levels added as the need for more space grew. The inhabitants likely expanded the city in response to increasing populations or external threats, deepening the tunnels and adding more rooms and storage areas as required.

Connections to Other Underground Cities
One of the most remarkable aspects of Derinkuyu is that it is part of a much larger network of underground cities in Cappadocia. Over 200 underground cities have been discovered in the region, with Derinkuyu being the largest and most famous. Some of these cities are connected by underground tunnels that stretch for miles, allowing inhabitants to move between different cities without ever coming to the surface.
The most famous connection is the tunnel between Derinkuyu and Kaymakli, another underground city located about 10 kilometers (6 miles) away. The existence of these tunnels suggests that the people of Cappadocia had developed a highly sophisticated system of underground infrastructure that allowed them to live and travel beneath the surface for extended periods.
Modern Rediscovery and Tourism
Derinkuyu remained hidden for centuries until its accidental discovery in 1963. Since then, archaeologists have been working to explore and map the vast underground city, though not all levels have been fully excavated. The site has become a popular tourist destination, attracting visitors from around the world who are fascinated by its mystery and grandeur.
Today, Derinkuyu is a protected historical site, and visitors can explore several levels of the city. However, the deeper levels remain off-limits due to safety concerns. The site is a UNESCO World Heritage site, along with other historical locations in Cappadocia, due to its historical significance and unique geological features.
Mysteries and Theories About Derinkuyu
Despite extensive research, many mysteries remain about Derinkuyu, particularly regarding its origins and the full extent of its underground network. Some historians and archaeologists believe that only a small portion of the city has been uncovered and that there may be deeper levels or additional connections to other underground cities that have yet to be discovered.
Additionally, questions remain about the exact purpose of the city and how it was used throughout history. While it is generally agreed that Derinkuyu served as a refuge, the complexity and scale of the city suggest that it was more than just a temporary hiding place. Some historians believe that it may have been used as a permanent or semi-permanent residence for certain groups, particularly during periods of conflict or persecution.
Conclusion: A Testament to Ancient Ingenuity
The Derinkuyu Underground City stands as a testament to the ingenuity and resilience of the ancient civilizations that built it. This vast subterranean metropolis served as a refuge, a community, and a fortress for those who sought protection from the dangers above ground.
