The temple in the village of Ostrovskoye is its main attraction and adornment. It was originally built of wood in 1711, and in 1905 it was rebuilt in stone. The five-domed Church of the Epiphany stands out with its bright and colorful decor and is a monument of regional architectural significance.

During the Civil War, a shell from the Reds damaged the bell tower, but the Cossacks managed to protect the church from closure and repurposing. Despite this, on March 16, 1931, the church was still closed. In 1934, it was severely damaged in a fire, and it was only reopened in 1946. The temple miraculously survived. Currently, renovation work is underway, and services are held on Sundays and holidays in a temporarily arranged prayer house.
