This study addresses the structure of cemeteries and types of tombstones in the funerary tradition of the Russian Priestless Old Believers (known as Bespopovtsy) living in the Ust-Tsilma District of the Komi Republic. For the first time, a description of their graveyards, known as “mogilniki”, or “mogily”, is provided, and their history and preservation are outlined. Traditional beliefs concerning cemeteries and their arrangement are cited. The symbolism of the forms of tomb structures, reproducing not only canonical prescriptions and requirements, but also certain pre-Christian beliefs, is analyzed in detail. Folk terms relating to the dead and the afterlife are included. The degree and nature of post-revolutionary transformations, profoundly affecting the foundations of the Old Believers’culture, are explored. Despite the attempts to preserve traditions, modern lifestyles took root in the 1960s and 1970s. Elements of local specificity in funerary rites have nonetheless survived and can be seen in the symbolism of tombstones, synthesizing Christian and pre-Christian traditions. Findings of ethnographic, linguistic, and archival studies are presented.
