legendary-scholar:In 1963, while doing renovations on his home, a man broke through an exterior bedroom wall in his home and discovered a tunnel entrance. What he found behind that wall stunned historians, archeologists and the world. The lost ancient underground city of Derinkuyu had been discovered.A multilevel series of rooms, carved from the soft volcanic rock in the Cappadocia region of Turkey, Derinkuyu extends to a depth of over 200ft. Believed to have been constructed by the Phrygians, an Indo-European people originally from the Balkan region, it dates back to the 8th Century BCE. Capable of holding up to 20,000 people, Derinkuyu had rooms for food stores, livestock, schools, kitchens, living and sleeping quarters and sanitary facilities. Small tunnels carved up to the surface allowed ventilation throughout the city. Entrance tunnels were carefully hidden in the hills surrounding Derinkuyu and connected to the city. One of these tunnels were discovered in 1963 when workers removed the bedroom wall.It is believed the city was originally carved as an escape from marauding Arab armies in 9th Century BCE and continued over the next several hundred years. The city was used often as a refuge during the Byzantine Era of the 5th through the 10 Century CE. -- source link
