the octahedral frame with four two-stage side attachments (, "prirub" from "rubit" meaning "to cut wood"). The eastern prirub has a pentagonal shape and contains the altar. Two smaller octagons of similar shape are mounted on top of the main octagon. The structure is covered in 22 domes of different size and shape, which run from the top to the sides. The refectory is covered with a three-slope roof. In the 19th century, the church was decorated with batten and some parts were covered with steel. It was restored to its original design in the 1950s. The church framework rests on a stone base without a deep foundation, except for the western aisle for which a foundation was built in 1870. Most wood is pine with spruce planks on the flat roofs. The domes are covered in aspen. The iconostasis has four levels () and contains 102 icons. It is dated to the second half of the 18th – early 19th century. The icons are from three periods: the two oldest icons, "The Transfiguration" () and "Intercession" () are from the late 17th century and are typical of the northern style. The central icons are from the second half of the 18th century and are also of the local style. Most icons of the three upper tiers are of the late 18th century, brought from various parts of Russia. The Church of the Intercession The Church of the Intercession () is a heated ("winter") church where services are held from October 1 until Easter. The church was the first on the island after a fire in the late 17th century destroyed all previous churches. It was first built in 1694 as a single-dome structure, then reconstructed in 1720–1749 and in 1764 rebuilt into its present 9-dome design as an architectural echo of the main Transfiguration Church. It stands 32 meters tall with a 26×8 meter perimeter. There are nine domes, one larger in the center, surrounded by eight smaller ones. Decoration is scant. A high single-part porch leads into the four interior parts of the church. As in the Transfiguration Church, the altar is placed in the eastern part shaped as a pentagon. The original iconostasis was replaced at the end of the 19th century and is lost; it was rebuilt in the 1950s to the original style. Belfry The original bell-tower rapidly deteriorated and was re-built in 1862 and
