This Huge Ancient Underground City Once Housed 20,000 People

If you’re like us, when you were a kid you dreamt about opening a door in your bedroom that lead to a hidden world.  But we’ve found one better… can you imagine a buried city laying just behind the walls of your house? In 1963, a Turkish man knocked down a wall in his basement, only to discover the ancient 18-story underground city of Derinkuyu.

At one time housing up to 20,000 people, Derinkuyu is one of the largest underground cities in the world. Located in Turkey’s Cappadocia region, it’s one of over 200 subterranean cities that were carved into the volcanic rock. In fact, Derinkuyu is connected to some of these subterranean settlements by tunnels that run for miles. Part of what makes it so impressive is the city’s depth of over 250 feet, as well as the organization needed to meet the demands of a population living underground. 

When was the underground city created?

It’s thought that the Derinkuyu underground city was started by the Phrygians, an Indo-European people, in the 8th to 7th centuries BCE. After the population became Christian in Roman times, they began to include chapels in their underground dwellings. It’s thought that the Christian population used the underground city to escape persecution by the Romans.

But it is during the Byzantine period that the underground city flourished. During the Arab-Byzantine wars from 780 to 1180 Derinkuyu was used as a refuge for Muslim Arabs—it was during this period that the tunnels connecting the subterranean cities were added.

An alternate theory places the creation of the underground city much earlier, with the ancient Anatolian Hittites. This placed construction at about 15th century BC, with the area being used to flee invading enemies.

What was life like in Derinkuyu?

Though not ideal for the claustrophobic, these ancient cultures tried to make life as comfortable—and safe—as possible in the underground city. Long shafts measuring up to 180 feet provided ventilation, while large, round stone doors weighing up to 1,000 pounds ensured that invaders could not gain entry into the underground city.

Aside from chapels for worship, there are also areas for livestock and numerous wells to provide drinking water. Communal rooms, stables, wine cellars, and oil presses all point to a vibrant replication of aboveground life below the earth. And what about all the waste? That was stored in pots and then transported aboveground whenever possible.

Derinkuyu Today

Open to the public since 1965, the Derinkuyu underground city, along with nearby Kaymaklı, is a well-known tourist attraction in the region. While only 8 of the 18 levels are viewable, it’s an incredible opportunity to see man’s ability to adapt to their circumstances.
