In the village of Osinki, there is a historical monument known as the "holy well and the graves of the burned." This site dates back to the 18th century. According to information provided by Anton Afanasyev, the monks of the Osinki skete, unwilling to submit to the destroyers of Peter's time, committed self-immolation in their dugouts. Five pillars have been erected at the site where their cells once stood, and they are carefully maintained. There is also a well inside the chapel where anyone can draw water, and a wooden path leads to the chapel.
