A long-lost underground city dating back 5,000 years has been discovered in Turkey after workers went to investigate the source of flooding affecting homes in the central Nevşehir province.
The discovery was made after locals living in the Çalış township of Avanos complained of flooding, the source of which could not be found. During their investigations, municipal workers opened up at tunnel that had been closed off for safety reasons decades earlier., when the crew ventured inside, they found the underground city partially submerged in clear water. The flooded rooms of the city were found to be directly beneath the houses that had experienced flooding.
At the end of 2014, a 5,000-year-old city around the Nevşehir Fortress was discovered during construction work. The huge network is thought to have been home to thousands of people who are thought to have been part of a farming community that existed around 3,000 BC., the city stretches over four miles, with tunnels wide enough for a car to pass through.
