Mystery of Underground Cities: Derinkuyu and Kaymaklı
Published: June 27, 2025 | Reading Time: 7 minutes
These cities, built layer by layer under the surface like an inverted skyscraper, are engineering marvels that amaze those who see them. Hidden beneath the rolling hills of Cappadocia lie some of humanity's most remarkable architectural achievements – vast underground cities that once sheltered thousands of people.
Imagine descending into the earth and discovering an entire civilization carved from solid rock. These aren't simple caves or tunnels, but sophisticated urban complexes with living quarters, churches, storage rooms, stables, and even schools. The underground cities of Cappadocia represent one of the most extraordinary examples of human ingenuity and survival instinct.
🏛️ Ancient Underground Metropolises
Cappadocia is home to over 200 underground cities, with 40 having at least three levels. The largest and most famous are Derinkuyu and Kaymaklı, both UNESCO World Heritage Sites that showcase the incredible engineering skills of ancient civilizations.
The History Behind the Underground Cities
The story of these underground cities spans millennia:
📜 Historical Timeline
- 8th-7th century BC: Phrygians begin carving the first underground spaces
- 4th century AD: Early Christians expand and develop the cities
- 7th-10th century AD: Byzantine period sees major expansions
- Arab raids (7th-10th century): Cities used as refuges
- 1960s: Modern rediscovery and archaeological excavation
These cities weren't built overnight. They evolved over centuries, with each generation adding new rooms, levels, and sophisticated systems. What started as simple storage spaces eventually became complex urban environments capable of housing entire communities for months at a time.

Engineering Marvels
The engineering achievements of these underground cities are remarkable:
Ventilation Systems
The most impressive feature is the ventilation system. Fresh air was circulated throughout the entire complex using a network of shafts and chambers. The system was so efficient that even the deepest levels had fresh air circulation.
Water Management
Underground cities had sophisticated water systems including wells, cisterns, and drainage. Water was carefully managed and distributed throughout the complex, with separate systems for drinking water and waste removal.
Security Features
Massive rolling stone doors could be moved from inside to seal off sections. These doors were designed to be impossible to move from the outside, providing perfect security for the inhabitants.
Communication Networks
Complex tunnel systems connected different areas and even different cities. Messages and people could move secretly throughout the underground network.
Daily Life Underground
Life in these underground cities was surprisingly organized and comfortable:
- Living Quarters: Families had private rooms with sleeping areas
- Communal Kitchens: Shared cooking spaces with ventilation
- Storage Areas: Large rooms for food, wine, and supplies
- Workshops: Spaces for crafts, tool making, and repairs
- Schools: Educational areas for children
- Churches: Religious spaces for worship and community gatherings
- Cemeteries: Burial areas within the complex
Why Were They Built?
Several factors led to the creation of these underground cities:
- Protection: Defense against Arab raids and invasions
- Religious Freedom: Safe spaces for Christian communities
- Climate: Stable underground temperatures year-round
- Resources: Storage for food and water during sieges
- Strategic Location: Control of important trade routes
