Goreme Valley’s story begins millions of years ago with dramatic geological events. Powerful volcanic eruptions from Mount Erciyes, Mount Hasan, and Mount Güllüdağ blanketed the region in thick layers of ash. Over time, this ash hardened into soft tuff rock, while wind and water slowly sculpted it into the fairy chimneys, valleys, and cones seen today. This unusually workable stone would later shape how people lived, worshipped, and survived in Cappadocia.
