The region of Cappadocia in central Turkey is home to one of the most spectacular landscapes in the world – deep valleys and soaring rock formations dotted with homes, chapels, tombs, temples and entire subterranean cities harmoniously carved into the natural landforms. Cities, empires and religions have risen and fallen around these unique underground havens, and yet it seems they still hold a few more secrets. Archaeologists in Turkey have uncovered another massive underground city in Cappadocia, consisting of at least 7 kilometers (3.5 miles) of tunnels, hidden churches, and escape galleries dating back around 5,000 years.
