A Turkish homeowner chasing his chickens through a hole in his basement during renovations came across an abandoned underground Turkish city that once housed 20,000 people.
Excavation work uncovered an incredible marvel of engineering, a network of tunnels and shelters 18 levels deep that went down 280ft (85 metres). This enormous underground city is thought to have begun life as a system of caves built back 1200 BC by the Hitтιтes to shelter from the Phrygians, who then in turn further excavated the area and expanded the living space when they conquered the region.
In later centuries it appears as though Christian inhabitants of the Roman Empire expanded the cave systems by adding more layers and including chapels, stables and places to make wine and olive oil.
The underground city of Derinkuyu was a safe haven for the people living in the region on many occasions, with a long string of conquerors and occupiers marching through that part of the world.
Turkish man knocked down basement wall to find 2,000-year-old underground city — after chasing his chickens through a hole
A Turkish homeowner chasing his chickens through a hole in his basement during renovations came across an abandoned underground Turkish city that once housed 20,000 people.
In an effort to recapture his escaping poultry, the unidentified man knocked down the wall in the 1960s to reveal a dark tunnel leading to the ancient city of Elengubu, known today as Derinkuyu.
Derinkuyu, burrowed more than 280 feet beneath the Central Anatolian region of Cappadocia, is the largest excavated underground city in the world and is believed to connect to more than 200 smaller, separate underground cities that were discovered in recent decades, Turkish guides told the BBC.
Inside the subterranean city — whose entrances connect to more than 600 private homes in the modern, surface-level region of Cappadocia — researchers found 18 levels of tunnels containing dwellings, dry food storage, cattle stables, schools, wineries, and even a chapel.
The city was also equipped with a ventilation system that supplied its residents with fresh air and water.
“Life underground was probably very difficult,” the guide, identified as Suleman, told the outlet.
“The residents relieved themselves in sealed clay jars, lived by torchlight, and disposed of ᴅᴇᴀᴅ bodies in [designated] areas.”
The exact date the impressive city was built remains contested, but ancient writings dating back to 370 BC indicate Derinkuyu was in existence.
The city was likely originally used to store goods but was then used as a bunker to escape from foreign invaders — the dimly lit hallways were intentionally built narrow and low so intruders would be forced to stoop and enter in single file.
The doors connecting each level were blocked by half-ton boulders only moveable from the inside that contained a small hole that allowed residents to spear the confined trespᴀssers.
Though it remains a mystery who the architects were, researchers believe the Hitтιтes — a Bronze Age Anatolian people — “may have excavated the first few levels in the rock when they came under attack from the Phrygians around 1200 BCE,” A. Bertini, an expert in Mediterranean cave dwellings, wrote in his 2010 essay on regional cave architecture.
The Phrygian invaders, an Indo-European-speaking empire that ruled Anatolia for 600 years, are credited with building the bulk of the city in the centuries before Derinkuyu changed hands several more times, including between the Persians, Christians and Cappadocian Greeks.
The city likely reached its peak population of 20,000 during the 7th-century Islamic raids on the Christian Byzantine Empire, the BBC reported.
After 2,000 years of use, Derinkuyu was finally abandoned in 1923 by the Cappadocian Greeks, who faced defeat in the Greco-Turkish war and escaped to Greece.
One century after it was rediscovered, the ancient city is open to visitors curious to experience life underground in Derinkuyu, which was added to the Unesco World Heritage list in 1985.
