This chapter presents a brief explanation of Cappadocia’s geological and geomorphological characteristics followed by an overview of the rock-cut structures and studies on those rock-cut structures found not only in the Cappadocia region but throughout Turkey. There are thousands of these artificial cavities and most of them have not been extensively studied. An inventory that includes all of them is not yet available. Following that, a broad summary will be presented of the existing research and studies on rock-cut architecture in the Cappadocia region in general and Kayseri, in particular. In the last two sections, brief information is given regarding all previous research and surveys on the artificial cavity, including Kayseri Underground Structures Inventory Project carried out by OBRUK Cave Research Group, and then the geological, historical, and geographical features of Koramaz Valley, which is the subject of this book, are explained.
