formations resembling chimneys, cones and pinnacles. Natural processes such as ancient volcanic eruptions and erosion have all sculpted these odd formations over the ages. Thousands of years ago, mankind added remarkable touches to the landscape by carving out houses, churches and underground cities from the soft rock. The Hittites were the first to chisel out underground tunnel complexes, seeking safety from invading Persians and Greeks. Much later Christians sought refuge in Cappadocia’s tunnels and caves. Today, some of the caves in the region are actually hotels and cater to tourists.
