On August 12, 1859, an amazing event occurred in the village: the image of Christ the Savior miraculously appeared on the Kazan Icon of the Mother of God in the local church. The first to notice this was Nikolai Petrovich Shelashnikov, a local landowner and actual state councilor. On August 22, during the all-night service, people saw bright rays in the sky, and then two large red columns of light appeared above the place where a spring would later emerge. Soon, a source of water gushed forth at this spot, which the residents of Isakly venerate as holy.

In 1905, the population of Isakly consisted of descendants of the archers resettled during Peter I's reign. They used the clean, soft, and tasty spring water from the surroundings of the Isaklinka River for drinking.

On October 12, 2005, the spring was reopened in honor of the Savior Not Made by Hands. Priest Vladimir Kaygorodov conducted a water blessing service. Thanks to the efforts of the authorities, a beautiful chapel, bathing area, and fence were built at the spring.
