Cappadocia
A semi-arid region in central Turkey, is full of extraordinary natural sites, most notably the “fairy chimneys,” tall, conical rock formations clustered in Monks Valley and elsewhere. Popular for exploration are the Bronze Age homes carved into valley walls by troglodytes (cave dwellers) and later used as refuge by early Christians. The 100 meter-deep Ihlara Canyon is home to numerous rock-face churches.
