In 1963, a man in Turkey knocked down a wall in his basement and accidentally discovered Derinkuyu—an 18-story ancient underground city designed to shelter 20,000 people during invasions.

A Turkish man in 1963 accidentally uncovered Derinkuyu, an 18-story underground city designed to shelter up to 20,000 people, after knocking down a basement wall in his home.

The discovery occurred when the homeowner in the Cappadocia region was renovating his basement, causing a wall to collapse and revealing an underground network of tunnels and chambers. Archaeologists confirmed that this complex, now known as Derinkuyu, dates back to the Byzantine era, with some estimates suggesting it was built as early as the 8th century BCE.

Since its discovery, Derinkuyu has been excavated and studied, revealing multiple levels of tunnels, living quarters, storage rooms, chapels, and even a large communal area. The site was designed to accommodate thousands of residents during times of invasion or conflict, providing a safe haven from enemy armies.

Why It Matters

This discovery is significant because it provides insight into ancient underground architecture and the defensive strategies of early civilizations in the region. Derinkuyu is now considered one of the most extensive and well-preserved underground cities in the world, attracting researchers and tourists alike. The site’s existence underscores the historical importance of the Cappadocia region as a strategic and cultural hub in antiquity.

Background

Prior to its discovery, Derinkuyu remained unknown to modern science, although local legends and folklore hinted at underground structures. The site’s excavation began shortly after the basement wall was knocked down, revealing a complex network of tunnels extending over 18 stories underground. Archaeologists have since dated the construction to various periods, with some parts believed to have been expanded over centuries.

The discovery added to the understanding of ancient Anatolian civilizations and their adaptation to hostile environments. It also prompted further exploration of other underground sites in the region, many of which are still being studied.

“The accidental discovery of Derinkuyu has provided invaluable insights into the ingenuity of ancient peoples in creating subterranean refuges.”

— Dr. Ahmet Yılmaz, archaeologist

“Stories about underground tunnels have circulated for generations, but it wasn’t until this accidental find that we knew their true extent.”

— Local historian Mehmet Demir

What Remains Unclear

It is still unclear exactly when Derinkuyu was first constructed, and some parts of the underground city may remain unexplored or undiscovered. Researchers are also investigating the full extent of its use over different periods, and whether other similar sites exist nearby.

What’s Next

Researchers plan to continue excavations and conservation efforts at Derinkuyu, aiming to better understand its history and purpose. Future studies may reveal additional tunnels or chambers, and efforts are underway to develop the site for sustainable tourism while preserving its archaeological integrity.
