Cappadocia’s history dated back to 5th century and documented onwards from that period. The region has dozens of underground cities; some complexes have as many as eight layers of interior levels. Kaymakli underground city is one amongst many underground dwellings in the area called Goreme, in Cappadocia. It was a unique underground structure built thousands of years ago with a depth of 85 metres. This underground city was huge with its long narrow tunnels, churches and winery. There were rooms for people to live in, storage space for their food and mortar. During the construction of the underground city, importance was given to proper ventilation and safeguarding its residents and their belongings from enemies and harsh weather.
