The analysis carried out in the article showed that the sacred architecture of Ingushetia is represented not by separate objects, but by sacred complexes, which always include three objects of worship, corresponding to the triune deity appearing in three persons: the main male deity, the secondary male deity and the female deity. The second conclusion related to the first, all sacred complexes of Ingushetia can be attributed to Christian architecture. Four groups of sacred complexes were identified: the temple of Thaba-Erda, general atronymic significance, patronymic significance, generic complexes. The last two groups are discussed in detail. It was revealed that sacred complexes reflect the processes of nativization of Christianity, both in the interaction of Christian and pagan mythology, and in the deification of the nature of a particular place. The architecture of each object individually may seem primitive, but the architecture of the entire complex as a whole, including the path from object to object, views of the surrounding space of mountains and gorges, a system of sacred trees and stones along this path, the movement of the sun is a unique phenomenon.
