Derinkuyu Underground City is the deepest excavated subterranean city in the Cappadocia region of Turkey, extending approximately 280 feet (85 meters) below the surface. Originally carved by Phrygians in the 8th–7th centuries B.C. and later expanded by Christians fleeing Roman and Arab persecution, this engineering marvel comprises 18 distinct levels (8 of which are accessible to tourists). Capable of sheltering 20,000 inhabitants alongside their livestock and food supplies, Derinkuyu features sophisticated ventilation shafts, defensive rolling stone doors, wineries, chapels, and a missionary school.
The Secrets beneath the Stone: An Introduction
Imagine standing in a stone kitchen 280 feet below the Earth’s surface, knowing that 20,000 people once lived right here—hidden in total darkness—without seeing the sun for months at a time. While the hot air balloons floating over fairy chimneys capture the imagination of most visitors to Cappadocia, the region’s true mystery lies deep beneath the soil.
Among the 200+ underground settlements discovered in the region, Derinkuyu stands out not just for its depth, but for its complexity. It wasn’t merely a hiding spot; it was a fully functioning subterranean metropolis. Based on One Nation Travel’s 15 years of experience guiding history enthusiasts through this region, we can confirm that Derinkuyu offers the most intense and atmospheric glimpse into the lives of the early Christians who called these tunnels home.
The History of Survival
The soft volcanic rock of Cappadocia made it easy for ancient civilizations to carve out homes, but the primary motivation for going underground was survival.
Who Built Derinkuyu?
While exact origins are debated, archaeologists believe the Phrygians started the excavation. However, it was during the Byzantine era that the city flourished. Early Christians expanded the tunnels to escape persecution from the Roman Empire and later used them as protection during the Arab-Byzantine wars.
The city was designed with defense in mind. The corridors are intentionally narrow to force invaders to walk single file, and massive circular stone doors—weighing up to 1,000 pounds—could only be rolled shut from the inside, effectively sealing off each floor.
What You Will Discover Inside
Descending into Derinkuyu Underground City is like stepping back into a forgotten world. The temperature remains cool and constant, and the air is surprisingly fresh, thanks to the ancient engineering that still functions today.
1. The Engineering Marvels
The city is centered around a massive ventilation shaft that reaches 180 feet deep. This shaft served a dual purpose: providing oxygen to all levels and acting as a well for water. Even during sieges, the residents had access to fresh water without ever surfacing.
2. Living Quarters and Daily Life
As you explore the first few levels, you will encounter the spaces where daily life occurred:
- Stables: Located on the first floor to reduce the smell and difficulty of moving livestock.
- Kitchens and Wineries: Blackened ceilings indicate where communal cooking took place. You will also see designated areas for pressing grapes and storing wine.
- Storage Rooms: Hundreds of carved niches were used to store grain and oil, essential for surviving months-long sieges.
3. The Missionary School
Located on the second floor is a spacious room with a barrel-vaulted ceiling. This is believed to have been a religious school. Adjacent to it are small study rooms, proving that education and faith remained priorities even in the direst circumstances.
Derinkuyu vs. Kaymakli: Which Should You Visit?
Travelers often debate between visiting Derinkuyu or its sister city, Kaymakli Underground City. While both are connected by a 9-kilometer tunnel (currently impassable), they offer different experiences.
| Feature | Derinkuyu Underground City | Kaymakli Underground City |
| Depth | 85 meters (approx. 8 levels open) | 20 meters (4 levels open) |
| Crowds | Can be busy, but spreads out due to depth | Often more crowded due to tighter spaces |
| Passageways | Narrower, steeper tunnels | Wider, more horizontal layout |
| Best For | Adventure seekers & history buffs | Those who prefer less climbing |
| Key Feature | The Missionary School & Depth | The large storage areas & wineries |
Our expert guides recommend: If you are physically fit and want to see the sheer scale of engineering, choose Derinkuyu. If you prefer a slightly less strenuous exploration, Kaymakli is a great alternative.
Practical Tips for Your Visit
Navigating the depths requires some preparation. We’ve found through our operations that prepared guests enjoy the experience much more.
- Watch Your Head: The ceilings are low, and tunnels can be as low as 5 feet (1.5 meters).
- Claustrophobia Warning: If you suffer from claustrophobia, this visit may be challenging. The tunnels are tight and enclosed.
- Footwear Matters: The stone floors are uneven and can be slippery. Wear sturdy walking shoes with good grip.
- Timing: To avoid the biggest crowds, try to arrive early in the morning (around opening time at 8:00 AM) or late in the afternoon.
