Beneath a quiet town on the Cappadocian plain lies one of the most astonishing structures ever carved by human hands: Derinkuyu, the deepest excavated underground city in Turkey. Reaching roughly 85 metres below the surface, this multi-level labyrinth of tunnels, homes, stables and churches could shelter thousands of people — completely hidden from the world above.
Visiting an underground city is, for many travellers, the moment Cappadocia stops being just a pretty landscape and becomes something stranger and far older. This guide covers Derinkuyu's history, what you will see inside, how it compares to Kaymaklı, and everything practical — including an honest answer to the question everyone asks: “Will I feel claustrophobic?”
What Is Derinkuyu?
Derinkuyu (“deep well” in Turkish) is a vast underground settlement carved into the soft volcanic rock about 30 km south of Nevşehir. Of its estimated 18 levels, 8 are open to visitors today, descending about 85 metres — roughly the height of a 25-storey building, straight down.
At its peak, estimates suggest the city could shelter up to 20,000 people together with their livestock and food stores. It was not a place where people lived permanently; it was a refuge — a city-sized panic room where entire communities could disappear for weeks when danger swept across the plain.
A City Hidden for Centuries
Nobody knows exactly who dug the first tunnels. The oldest sections may date back to the Phrygians around the 8th–7th centuries BC, and some historians point to even earlier Anatolian origins. What is certain is that the city reached its full extent in the Byzantine era, when Christian communities expanded it into a sophisticated refuge during the Arab–Byzantine wars of the 7th to 10th centuries.
When raiding armies approached, villagers descended with their animals, sealed the tunnels behind them with massive rolling stone doors, and simply waited. Attackers found empty villages above and near-impenetrable darkness below.
Then the city was forgotten. For centuries, locals knew only of odd cool cellars beneath their houses. In 1963, a resident of Derinkuyu renovating his home broke through a wall and found a tunnel — which led to another, and another. Excavations revealed the enormous city below, and it opened to visitors in 1969.
What You'll See Inside
The visitor route winds down through progressively deeper levels, each with a distinct purpose:
- Stables near the surface, where animals were kept (their body heat also helped warm the upper levels).
- Kitchens and wineries with soot-blackened ceilings, rock-cut storage jars and grape-pressing basins.
- A missionary school on the second level, with a distinctive barrel-vaulted ceiling — a rare luxury in a hand-carved city.
- Rolling stone doors: huge circular stones weighing up to half a tonne that could seal each level from the inside. Attackers could not open them from outside.
- Ventilation shafts plunging through every level — the deepest also served as wells, safe from poisoning because they were invisible from the surface.
- A cruciform church on the lowest open level, carved in the shape of a cross, and small chapels along the way.
Look closely at the walls as you descend: you can still see the individual chisel marks of the people who carved this city out of solid rock.
An Engineering Marvel: How Did People Breathe Down There?
Derinkuyu's most impressive feature is invisible: its ventilation. More than fifty vertical shafts pull fresh air down through every level, keeping the air breathable even 85 metres underground and holding the temperature at a constant, cave-cool 13–15°C all year round. The system works so well that you will feel a gentle air current in many corridors even today. Some passages are believed to connect Derinkuyu to the Kaymaklı underground city, several kilometres away — a tunnel network that has never been fully mapped.
Derinkuyu vs Kaymaklı: Which One Should You Visit?
The two most-visited underground cities are often compared:
- Derinkuyu is the deepest, with a dramatic vertical descent, the barrel-vaulted school and the cruciform church. Its passages are narrower and steeper — more adventurous, more atmospheric.
- Kaymaklı is wider and more horizontal, spread across fewer open levels with broader tunnels. It is often the more comfortable choice for families and visitors unsure about tight spaces.
If you want the strongest “lost world” feeling, choose Derinkuyu. If low ceilings worry you, Kaymaklı is gentler. Either way, you will understand why these cities amaze archaeologists. Our dedicated Underground City Tour takes the guesswork out of logistics, and the classic Green Tour combines an underground city with the Ihlara Valley in a single day — see our Red Tour vs Green Tour comparison for how it fits into a typical trip.
Is Derinkuyu Claustrophobic? An Honest Answer
Some sections are genuinely tight: connecting tunnels between levels can be around a metre high, forcing you to walk bent over in single file for stretches of 10–20 metres. The route is one-way in the narrow parts, well lit, and clearly marked with arrows, and you are never far from a larger chamber where you can stand upright and breathe.
Most visitors — including many who were nervous beforehand — do fine and love it. But if you have serious claustrophobia, heart or knee problems, or difficulty crouching, consider staying with the upper levels or choosing Kaymaklı's wider passages instead. Children, on the other hand, usually think it is the best thing in Cappadocia.
Tickets, Opening Hours and Getting There
- Opening hours: typically 8:00–17:00 in winter and until around 19:00 in summer, with last entry about an hour before closing.
- Tickets: prices for foreign visitors change frequently; budget roughly €13–15 and check current rates. The Museum Pass Cappadocia covers Derinkuyu along with the Göreme Open Air Museum and other state-run sites.
- What to wear: comfortable shoes with grip (floors are smooth-worn rock) and a light layer — it is a constant 13–15°C inside regardless of the weather above.
- Getting there: Derinkuyu is about 40 minutes' drive from Göreme. Public dolmuş minibuses run from Nevşehir, but connections from the tourist towns are slow — see our Cappadocia transportation guide for the details. Most visitors come with a guided tour, which includes hotel pickup and, crucially, a guide.
Why Visit with a Guide?
More than any other site in Cappadocia, an underground city needs storytelling. Without a guide, Derinkuyu is a sequence of dim rooms; with one, every niche becomes legible — this hollow was a lamp shelf, this groove channelled communication between levels, this stone sealed a family in safety. Our Underground City Tour and Green Tour both include expert local guides who bring the city back to life.
Frequently Asked Questions
How deep is Derinkuyu Underground City?
The excavated city reaches roughly 85 metres below the surface. Eight of its estimated eighteen levels are open to visitors.
How many people could live in Derinkuyu?
Estimates suggest the city could shelter up to 20,000 people along with livestock and food supplies during extended sieges.
How long does a visit take?
About one hour inside is typical, plus time above ground. As part of a guided day tour, Derinkuyu is usually combined with other highlights such as the Ihlara Valley.
Is Derinkuyu suitable for children?
Yes — children generally love it. The narrow passages are an adventure for them; just keep young children close, as the route has steps and low ceilings.
Derinkuyu or Kaymaklı — which is better?
Derinkuyu is deeper and more dramatic; Kaymaklı is wider and easier to move through. If tight spaces concern you, choose Kaymaklı; otherwise Derinkuyu offers the more memorable descent. See our detailed Derinkuyu vs Kaymaklı comparison.
