In the mid-17th century, among the free steppes and vast forests, peasants, migrants from the Volga region and central areas, founded the village of Troitskoye in 1775. It was a large village, on the territory of which there were once three churches. The first of them, the Church of Cosmas and Damian, was built in 1775 and became the first significant structure in the village.

From 1863 to 1865, the Kazan-Bogoroditskaya Church was erected in Troitskoye. In 1930, it was closed, and the building housed the district party committee, then a therapeutic department of the hospital, and later a nursing home.

The third church, the Church of the Exaltation of the Holy Cross, was built in the early 20th century with funds from the landowner Lapshin and was located at the other end of the village, which the locals called the Silk Region. The church existed until 1961, after which it was demolished. On November 17, 1891, a parish school opened next to it, where 28 boys and 8 girls studied. The first class was held in the church watchman's lodge, while the second and third classes were in a large merchant's house. The school existed in this form until 1918, after which primary schools were opened in the Andreevsky Khutor, in the Mezhurochye of Kupla, and in the center of the village of Troitskoye.

Today, only one church remains in the village, that of Cosmas and Damian. It is log-built and not particularly remarkable from the outside, but very beautiful inside. In the 1930s, it housed a grain storage facility, in 1950, a kindergarten, and from 1972, a pharmacy. Only in 1998 was the building returned to the faithful. The villagers restored the temple and improved the territory with their own efforts. Significant assistance in the restoration was provided by local resident Abrosimov M.G., who donated his savings for this purpose.
