Cappadocia is stunning not just above the surface, but also beneath the ground. There are underground cities that were created many centuries ago and some of them are more than ten levels deep. And no, these were not just used as temporary places of shelter but people lived here permanently. It gets even stranger – more than 40 underground cities have been discovered in Cappadocia and some of them are connected to each other via tunnels. These were hidden for many years and one of the biggest was discovered in 2014. As per some archeologists, they were created in the 1200s BC. Whoa!
