Underground Cities Around the World: What to Know

From Derinkuyu to Cappadocia tunnels—discover underground cities, their history, visiting tips, and what to expect on a tour.

Underground cities and large subterranean complexes tell stories of adaptation and shelter. From ancient cave dwellings to modern wartime bunkers, these sites require special care when visited. Below are notable underground places with practical visiting advice.

Derinkuyu, Turkey

Derinkuyu is a multi-level underground settlement carved into volcanic rock. Guided tours explain the complex ventilation and communal spaces. Visitors should be prepared for narrow passages and steps — those with claustrophobia may prefer guided surface tours.

Burlington Bunker, UK

A Cold War-era complex accessible by appointment. Visits are controlled and often require advance booking; photography rules may apply. Expect long corridors and low ceilings — comfortable walking shoes recommended.

Naours Caves, France

A former refuge and storage complex now adapted for family-friendly walks. Boardwalks and guided routes make it accessible to many visitors; ideal for learning about subterranean history without extreme physical demands.

Visiting Tips

• Book tours in advance for managed sites.
• Wear non-slip shoes; some floors can be wet or uneven.
• Carry a small light, though many tours provide illumination.
• Respect preservation rules — do not touch fragile surfaces.

Accessibility & Safety

Many underground sites have steps, narrow passages, and variable ventilation. Check site advisories for accessibility, and avoid visiting during respiratory illnesses or if you have mobility limitations that would make tight spaces hazardous.
