Cappadocia is a dream like place in central Anatolia Turkey, with ‘fairy chimneys’ (rock formations).
It has a very remarkable history. Volcanic eruptions created this surreal moonscape: the lava flows formed tuff rock, which wind and rain sculpted into sinuous valleys with curvy cliff faces and pointy fairy chimneys. Cappadocians chiselled homes in the soft rock, paving the way for cave-dwelling hippies and today’s boutique fairy-chimney hotels.
The local Christians were persecuted, first by the Romans and then raiding Muslims, and they often had to hide from hostile forces. When they heard hoof beats, they would abandon the cave churches and go underground – quite literally. Beneath Cappadocia’s rock formations is a network of subterranean cities, which housed up to 10,000 people each. The largest discovered are almost ten levels deep, with narrow passages connecting the floors like hamster tunnels.
