In this research paper will be analyzed troglodytic architecture in Cappadocia and especially the case of holy sites through the description of five monasteries and hermitages. Cappadocia is located in the Central Anatolia in modern Turkey. This is an area with special geological and architectural interest. In this despite the difficulty of rough and difficult terrain residents managed to create a distinctive architectural tradition.Besides, natural difficulties , this area experienced very strong movement due to the peaceful movement of races, or due to the many raids it has experienced as a result of its important place. These difficulties did not stopped the inhabitants from developing a special technique, and thus creating numerous villages, and some of them subterrain. Strong interest is shown due to the numerous monasteries and hermitages that exist in the area, which developed Cappadocia as a holy place, especially due to the establishment of Christianity as the new religion during the Byzantine Empire. Due to the technique that was developed originally for the survival of the inhabitants, church architecture and the art of iconography flourished. With the juxtaposition of five examples, which are the monastery Karanlik kale and convent Eskı Gümüş and hermitages of St. Nikitas Stylite, St. Simeon the Stylite and the band of Santa Barbara, the issue of harmony and integration of architectural creation in a hostile landscape like that of Cappadocia will be examined.
