The Nenets people have various forms of worshipping spirits in their sacred landscapes. The article examines the history, definitions, and classifications of forms of worship of the Nenets sacred places (khebidia ia). Cult structures (khekhe) include objects of nature as well as effigies of various deities installed at sacred sites or residential areas.
