In the ancient village of Orekhovo, at the sources of three rivers, stands the Church of the Life-Giving Trinity. This majestic stone structure was built in 1791 and significantly expanded in 1903 to accommodate all seven thousand residents of the village.

The people of Orekhovo, although not wealthy, were characterized by ambition and practicality. They endured hardships and deprivations during the construction, understanding that they were relieving their descendants of this burden. After all, maintaining a church is easier than building one. Today, the Orekhovo church is the largest in the Shchigrov diocese, and services have never ceased. They continue today, with prayers for all the builders, improvers, and benefactors.

At the beginning of the 20th century, with the population growth, the need to expand the church arose. The construction of a new refectory and bell tower began. The nobles Mikhail Obolonsky from the village of Vladimirovka and Sergey Tarasov from the village of Petrovskaya helped the people of Orekhovo by lending money for building materials, which the Orekhovo residents repaid through agricultural labor. In 1903, the new church building was consecrated. In 1916, another church, the Ascension Church, appeared in the Orekhovo volost in the village of Dolgusha.

However, soon heavy trials began for the country: world war, the overthrow of autocracy, revolution, civil war, and famine. To combat the effects of famine, the Trinity Church of the village of Orekhovo donated a silver cross, a chalice, a tabernacle, and other items weighing a total of 15 pounds and 59 zolotniks. The church of the village of Vladimirovka also surrendered valuables, while no confiscations were made in the Ascension Church of the village of Dolgusha, as there were no valuables there.

In 1923, Orekhovo became part of the Nizhnedvitsky district of the Voronezh province, and since 1934, it has been included in the Kastorensky district of the Kursk region, under the jurisdiction of the Kursk diocese. In November 1929, the priests of the Orekhovo church, Nikolai Korystin and Sergey Popov, were arrested on charges of counter-revolutionary activities. In the late 1930s, services were temporarily suspended, and the building was used for grain storage. In July 1942, the village was occupied by German troops for six months. After liberation, part of the church was handed over to the community of believers, while the other part was used by the local authorities. Since then, services in the church have not ceased. In the year of the Millennium of the Baptism of Rus, the parish received full control of the church.
