Where is the Oldest Underground in the World? Unearthing Ancient Secrets Below Our Feet
When we think about ancient wonders, we often picture towering pyramids, crumbling castles, or vast ruins open to the sky. But beneath the surface, hidden from plain sight, lies a different kind of history – the history of underground structures. For those curious about humanity's earliest architectural endeavors, the question arises: Where is the oldest underground in the world?
While the concept of "underground" can encompass many things, from mines to burial chambers to entire settlements, the answer to this question often points to a remarkable and ancient network of tunnels located in Turkey. Specifically, we're talking about the ancient city of Derinkuyu, nestled in the Cappadocia region of central Turkey.
Derinkuyu: A Subterranean Marvel
Derinkuyu is not just a single tunnel or a simple cave; it's a colossal, multi-level underground city that could house thousands of people and their livestock. Excavated between the 8th and 7th centuries BCE (though some estimates push its origins even further back, to the Hittite period around 1500 BCE), Derinkuyu represents an astonishing feat of engineering and a testament to the ingenuity of ancient peoples.
What Makes Derinkuyu So Significant?
- Depth and Scale: Derinkuyu extends approximately 60 meters (about 185 feet) deep into the earth and is believed to have been capable of sheltering up to 20,000 people along with livestock and provisions.
- Advanced Design: This wasn't a haphazard digging operation. The city features numerous ventilation shafts, wells, storage rooms, stables, chapels, and even wineries. There were large, rolling stone doors that could be used to seal off different levels, providing defense against invaders.
- Purpose: It's believed that Derinkuyu and similar underground cities in Cappadocia were primarily constructed as a defensive measure. The region was historically a crossroads and was vulnerable to raids and invasions. These subterranean shelters offered a safe haven, allowing entire communities to disappear beneath the surface for extended periods.
- Multiple Levels: The city is organized into at least 18 distinct levels, though only a portion has been excavated and is open to the public. The sheer complexity of its layout suggests a well-planned and organized society.
Who Built Derinkuyu?
The exact architects of Derinkuyu remain a subject of ongoing archaeological debate. Evidence suggests that the Hittites may have initiated the construction of some of the earliest levels. Later, the Phrygians, a people who inhabited Anatolia, are thought to have expanded upon these initial structures. Over centuries, different groups, including Persians and early Christians, continued to utilize and modify the underground complexes, adapting them to their own needs and adding their own architectural elements.
Why Build So Deep?
The primary motivation for building such extensive underground cities was protection. The Cappadocia region, with its soft volcanic rock, was ideal for excavation. However, the constant threat of war and invasion made living entirely on the surface perilous. These underground cities provided:
- Safety from Raiders: Large populations could be hidden away from marauders.
- Protection from Harsh Climates: The earth provided insulation against extreme temperatures, keeping inhabitants cool in summer and warm in winter.
- Resource Management: The ability to store food and water for long periods was crucial for survival during sieges.
Other Ancient Underground Structures
While Derinkuyu is widely considered the oldest and most extensive *city* discovered underground, it's important to acknowledge that humanity has a long history of creating subterranean spaces:
- Ancient Mines: Evidence of mining operations dates back tens of thousands of years. For example, the Swabian Jura region of Germany has yielded evidence of Neolithic flint mines dating to the 5th millennium BCE.
- Burial Sites: Many ancient cultures created elaborate underground tombs and burial chambers, such as the Egyptian pyramids (though their primary structures are above ground, they contain extensive underground passages and chambers) or the catacombs of Rome, which began to be used in the 2nd century CE.
- Early Settlements: In some regions, early human settlements were built into natural caves or partially excavated into hillsides for shelter and protection.
However, for a comprehensive, purpose-built, and incredibly ancient underground city that could house an entire population, Derinkuyu in Turkey stands as the most compelling answer to the question of where the oldest underground in the world is located.
The discovery of Derinkuyu and its neighboring underground cities like Kaymakli reveals a hidden chapter of human history, showcasing an extraordinary ability to adapt and thrive even in the face of constant threat.
FAQ: Your Questions Answered
How old is Derinkuyu, exactly?
While pinpointing an exact construction date is challenging, archaeological evidence suggests that the earliest parts of Derinkuyu were carved out between the 8th and 7th centuries BCE. Some researchers believe the initial excavations may even predate this, possibly back to the Hittite era around 1500 BCE.
Why are there so many underground cities in Cappadocia?
Cappadocia's unique geology, characterized by soft volcanic tuff rock, makes it exceptionally well-suited for excavation. Combined with the region's historical vulnerability to invasions, this geological advantage led to the development of numerous underground shelters and cities over centuries by various civilizations seeking refuge.
Could people live in Derinkuyu permanently?
Derinkuyu and similar underground cities were designed for temporary refuge, not permanent habitation. They provided essential resources like ventilation, water, and storage, allowing inhabitants to survive for months or even years during times of conflict or extreme weather. However, life underground was likely challenging and not intended as a long-term lifestyle.
What is the deepest underground city in the world?
Derinkuyu is generally considered the deepest and largest of the ancient underground cities in Cappadocia, reaching depths of approximately 60 meters (185 feet). While other cities in the region are also extensive, Derinkuyu stands out for its sheer scale and depth.
