The Chapel of the Sign of the Mother of God in the village of Korba, located in the Medvezhyegorsk district of the Republic of Karelia, has long been a subject of study, yet there is still no consensus on its construction history. Researchers have attempted to determine the dates of its construction and reconstructions by applying the method of comprehensive chronological attribution of wooden architecture monuments, which includes architectural and dendrochronological studies.

The construction dates of the chapel were established based on field surveys and typological analysis, using an architectural-archaeological scale for dating churches and chapels in Karelia. Data regarding the creation time of the icons from the 'icon shield' with the temple icon of the Sign of the Mother of God, the ceiling 'sky', as well as later icons from the 1940s were taken into account. Two construction periods were identified: the first, the erection of the prayer room and lowered narthex in the second half of the 18th century, and the second, the addition of the vestibule with a bell tower over its western part from the late 18th century to the first half of the 19th century.

Dendrochronological analysis showed that wood with wide layers and a small number of annual rings was used for construction, which complicated the precise dating of the samples. Two possible dates for the logging of the logs were obtained: 1765 or 1824; however, the presence of two construction phases was not identified. The discrepancies between architectural and dendrochronological data require further research. Currently, the formation of the chapel can be dated over a broad time interval from the second half of the 18th century to the first half of the 19th century, without the possibility of accurately determining the date of the second construction period due to the lack of specific confirmations of the time of reconstruction of the vestibule and bell tower.
