When you think of Cappadocia, Turkey, the first image that comes to mind is usually a sunrise sky filled with hundreds of colorful hot-air balloons drifting over surreal fairy chimneys. But while the view from above is breathtaking, another fascinating world lies completely hidden beneath the ground.
Deep under the unique landscape of Central Anatolia are vast, multi-level subterranean cities carved out of soft volcanic rock. Built thousands of years ago, these hidden complexes were designed to shield entire civilizations from invasion, harsh winters, and political turmoil.
If you are planning a trip to Turkey, stepping into these subterranean marvels is an absolute must. Here is your ultimate guide to exploring the underground cities of Cappadocia, their history, key sites to visit, and essential tips for planning your trip.
What Are Cappadocia’s Underground Cities?
Cappadocia’s underground cities are complex subterranean networks that once housed thousands of people. Unlike simple caves or hideouts, these were fully functioning ecosystems complete with living quarters, stables, kitchens, storage rooms, wine presses, churches, ventilation shafts, and defense mechanisms.
Why Were They Built?
The origins of these underground structures trace back as early as the Hittite era (around 1200 BCE). However, they were expanded significantly during the Byzantine era (8th to 12th centuries). Early Christian communities expanded these caves into massive defensive networks to hide from Roman persecution and later from Arab-Byzantine raids.
Whenever an invading army approached, thousands of locals would retreat subterraneanly, sealing themselves inside behind giant, rolling stone doors that could only be locked from the inside.
Top Underground Cities to Visit in Cappadocia
While archeologists have discovered over 200 underground settlements in the region, a few stand out as the most impressive and accessible for tourists.
UNDERGROUND CITIES AT A GLANCE
+------------------+-----------------------+--------------------------------+
| City | Primary Feature | Highlights |
+------------------+-----------------------+--------------------------------+
| Derinkuyu | Deepest (85 meters) | Underground school, 18 levels |
| Kaymakli | Widest footprint | Storage tunnels, copper foundry|
| Ozkonak | Clever defense traps | Communication pipes between levels |
+------------------+-----------------------+--------------------------------+
1. Derinkuyu Underground City (The Deepest)
Derinkuyu is the deepest excavated underground city in Turkey, plunging nearly 85 meters (280 feet) into the earth. It was large enough to house roughly 20,000 people along with their livestock and food supplies.
- What to See: An underground religious school, a large chapel with a cross-shaped plan, animal stables on the upper level, and a massive 55-meter-deep ventilation shaft.
- The Experience: Visiting Derinkuyu involves descending through narrow, winding staircases deep into the earth. It offers an incredible look at ancient structural engineering.
2. Kaymakli Underground City (The Widest)
Located about 10 kilometers north of Derinkuyu, Kaymakli is famous for being the widest underground city in the region. Around four of its eight levels are open to the public today.
- What to See: Intricate wine presses, cellars packed with storage jars, living quarters, and even a copper smelting workshop.
- The Experience: The tunnels here are slightly wider than Derinkuyu’s, making it a great option if you prefer a slightly less cramped layout while still seeing authentic subterranean life.
3. Ozkonak Underground City (The Hidden Gem)
Situated near Avanos, Ozkonak is smaller than Derinkuyu and Kaymakli, but it features unique architectural details not found elsewhere.
- What to See: Ozkonak features a unique pipe system above the stone doors used to dump hot oil or shoot arrows at invaders, as well as an early communication system built into the walls.
Architectural Marvels: How Ancient People Survived Underground
Living underground for weeks or months at a time required ingenious engineering. Here is how ancient inhabitants managed to survive:
- Ventilation Systems: Thousands of vertical air shafts brought fresh air down to the lowest levels, keeping oxygen flowing even deep underground.
- Water Sources: Wells were dug deep into subterranean aquifers. Crucially, some wells were not connected to the surface to prevent enemies from poisoning the water supply.
- Rolling Stone Doors: Heavy, circular stone doors—weighing up to half a ton—could be rolled across doorways in seconds. They featured a central hole through which defenders could poke spears.
- Subterranean Tunnels: Many underground cities were connected to each other through miles of long secret tunnels, allowing people to escape if one city fell.
Practical Tips for Visitors
To make the most of your underground journey, keep these helpful travel tips in mind:
- Wear Comfortable Shoes: Floor surfaces can be uneven, slick, or damp. Sturdy walking shoes or sneakers are essential.
- Watch Your Head: Tunnels can be low and narrow. If you are tall, be prepared to crouch while walking through certain passages.
- Bring a Light Jacket: Underground temperatures remain cool year-round (around 13°C to 15°C or 55°F to 59°F), regardless of how hot it is outside.
- Mind Claustrophobia: If you suffer from severe claustrophobia, stick to the main chambers or choose wider sites like Kaymakli.
- Hire a Local Guide: Having a guide explain what each room was used for brings the history to life far better than exploring on your own.
