The stone church dedicated to the great martyr Demetrius of Thessalonica was built in 1865 in the village of Kazachya Loknya, part of the Sudzha district of the Kursk diocese. The funds for its construction were collected by the pious residents of the village. The church, designed in a traditional style, amazed with its beauty and stability, symbolizing unwavering faith. It had three altars and a bell tower. The central altar was dedicated to the great martyr Demetrius of Thessalonica, the southern altar to St. Nicholas the Wonderworker, and the northern altar to the three hierarchs: Basil the Great, Gregory the Theologian, and John Chrysostom.

According to the document "Report on the Dmitriev Church in the Sudzha District of the Kursk Diocese for 1916," the parish had a priest, a deacon, and a psalmist. They did not receive a salary and lived on the income from the collection, which amounted to 480 rubles and 7 kopecks in 1916. The parish owned 32 desyatinas of land, but it was unsuitable for cultivation and located 7 versts from the church, bringing in an income of only 326 rubles. On the parish territory, there were a church school and a teacher training school that prepared educators for the entire Kursk province. Priest Father Ivan Sokolov left a good memory of himself, and in 1916, the parishioners built him a house at their own expense.

During the revolution, the church was closed and used as a warehouse. All church property, the priest's house, and the church watchman's house were confiscated by the new authorities. Father Ivan met a martyr's death at the hands of the Red Army soldiers, having endured long torture and torment before being shot.

The Church of the Great Martyr Demetrius of Thessalonica is an architectural monument. Currently, services are once again being held there, and parishioners are engaged in its restoration.
