Across borders - underground city

 Beneath the landscape of Cappadocia in Turkey lies one of history"s greatest mysteries: an entire city carved into the rock. This city, one of the most unique in the world, was designed for warfare. Comprising 18 underground levels, it is equipped with all the amenities necessary for its inhabitants to remain submerged for extended periods. Used for concealment and protection during times of war and invasion, this city stands as a testament to ancient architecture and humanity"s skillful use of the terrain to construct fortified and secure cities.
