“These two valleys have some of the finest painted Byzantine churches on earth,” David Barchard wrote in Cornucopia 11. “Walking through a virtual Garden of Eden with only nightingales for company, it is strange to think that these remote valleys may have been more thickly populated in the Dark Ages than they are now.” The valleys lie beneath Bozdağ mountain not far from Göreme, just over 2km from the village of Çavuşin. Some of the best examples of the rock churches, sanctuaries and cathedrals include the 11th century Bayaz Kilise (White Church) in Kızılçukur, which was discovered in 1989.
