The Church of the Transfiguration is not heated and is therefore called a summer church and does not hold winter services. Its altar was laid June 6, 1714, as inscribed on the cross located inside the church. This church was built on the site of the old one which was burnt by lightning. The builders names are unknown. A legend tells that the main builder used one axe for the whole construction, which he threw into the lake upon completion with the words "there was not and will be not another one to match it".
The church has 22 domes and with a height of 37 meters is one of the tallest wooden buildings of the Russian North. Its perimeter is 20×29 meters.
The church was built on a hill 4 meters above the Lake Onega level. Its major basic structural unit is a round log of Scots Pine (Pinus sylvestris) about 30 cm in diameter and 3 to 5 meters long. Many thousands of logs were brought for construction from the mainland, a complex logistical task in that time.
