The surface of the Earth is full of incredible places waiting to be explored, but sometimes the most captivating stories are hidden underground. Some of the world’s most mysterious underground cities house the most impressive and astonishing structures built by humanity throughout history. Constructed for various reasons—whether to escape war, for religious rituals, or to avoid natural disasters—these cities are marvels of engineering and hold historical mysteries. Let’s take a closer look at these mystical cities.
1. Derinkuyu, Turkey
Derinkuyu Underground City is buried within the unique landscape of Cappadocia and is known as one of the deepest underground cities in the world. Discovered by accident in 1963, this city plunges to a depth of 85 meters and can accommodate up to 20,000 people. It contains churches, kitchens, stables, educational spaces, and even wine cellars. Historians believe Derinkuyu was used by Persians and later Byzantines to protect themselves from invasions. Imagine a city so vast and equipped that thousands of people could survive underground for days!
2. Naours, France
Naours Underground City, located in northern France’s Picardie region, once served as a refuge for thousands of people fleeing wars. This extensive underground network spans about 3 kilometers and contains over 300 rooms. Active mainly during the 1600s, Naours also provided shelter for soldiers during World War I. Many inscriptions on the city’s walls, etched by soldiers of the time, give Naours a strong historical and emotional connection.
3. Edinburgh Vaults, Scotland
If you want to step into Edinburgh’s dark history, the Edinburgh Vaults are the place for you! Built in the 18th century, these underground tunnels and chambers were once used for trade and storage beneath the city. Over time, these dark tunnels and abandoned rooms became a haven for the people with low-income and criminals, inspiring numerous city legends and paranormal tales. The most famous ghost of the Vaults, Mr. Boots, is known to give visitors a fright. Walking heavily in the attics, this ghost sometimes touches people’s shoulders, leaving them startled. This sudden contact leaves many feeling deeply uneasy and chilled.
But that’s not all. In rooms where former criminals met their end, whispers can be heard. No one knows where these sounds come from, but the eerie conversations echoing in empty corridors send shivers down visitors’ spines. Some claim to feel dark figures watching them, while others report the ghost of a small child trying to interact with them, almost playfully touching them like a gust of cold wind. Walking through the Vaults at night takes courage—who knows, maybe you’ll encounter one of its ghosts yourself!
4. Petra, Jordan
Petra, a UNESCO World Heritage Site, is one of the most impressive archaeological sites in world history. While not entirely underground, Petra is a mesmerizing ancient city carved mostly into rock. Known as the capital of the ancient Nabatean civilization, it contains more than 3,000 caves, temples, and tombs. One of the city’s most famous structures, Al-Khazneh (The Treasury), is an enormous rock-carved building that once served as a major trading hub in the ancient world. Petra continues to enchant people with its historical legacy and awe-inspiring structures.
5. Coober Pedy, Australia
Coober Pedy stands out from other underground cities as it is still actively inhabited today. Located in southern Australia, this small town is known for being one of the hottest places on Earth. Due to the extreme heat, the population moved underground, building homes, churches, and even hotels beneath the surface. Coober Pedy is also known as the world’s opal capital, so in addition to being an underground city, it’s famous for precious gemstone mining.
6. Wieliczka Salt Mine, Poland
The Wieliczka Salt Mine in Poland, protected by UNESCO, offers much more than just salt extraction. Built in the 13th century, this massive underground complex is not only a salt mine but also a city filled with sculptures, chapels, and vast galleries. One of its most stunning structures is the Chapel of Saint Kinga, a breathtaking place of worship made entirely of salt. Recognized for its historical and cultural value, the Wieliczka Salt Mine is renowned as a fascinating underground wonder.
