The name of the Trinity Church in Bor comes from an ancient church that was located here. Initially, there was a women's monastery adjacent to the Borisoglebsky men's monastery. The first mentions of the Troitsky Monastery date back to the second half of the 16th century. Documents from the Borisoglebsky Monastery mention a donation from Ivan the Terrible for the forced tonsure of Princess Fotiniya, the widow of Prince Daniil Pronsky.

The monastery was small and included a wooden Trinity Church with an altar dedicated to Archangel Michael, a church of St. Nicholas, monastic cells, and a cemetery. The territory was enclosed by a wooden palisade, which remained until the 1820s. At that time, peasant Ivan Vasilyevich Shchepetilov built a new fence with seven towers and two gates. It is now in a ruined state. The monastery also served as a place of prayer for the residents of the surrounding settlements belonging to the Borisoglebsky Monastery. After Catherine II's reform, the settlements were transferred to Count Orlov, and the Trinity Church became a parish church. Since 1840, the parish became the center of the deanery. In the 1730s, with the funds of the parishioners, a three-tier stone bell tower with a high spire was built.

According to data from the "Rostov District of Yaroslavl Province," the church was once supported by Praskovya Alexeyevna Naryshkina. Before taking the veil, she built a new church building and donated many gifts, including a silver cross and liturgical items. Nearby was a small forest called "Bozhedomka," where those who died suddenly were buried.

In the 20th century, the fate of the Trinity Church turned tragic. In 1930, it became the center of the renovationist movement, and out of 52 churches in the area, 19 became renovationist. In 1935, the church was closed, and priest Georgy Komkov was arrested and shot in 1937. The church building housed a cafeteria and a club, and some gravestones were used for construction. In 1942, the church burned down, and later it was dismantled for bricks.

In 1994, the complex of the Trinity-Bor Monastery was returned to the Borisoglebsky Monastery. The altar wall, bell tower, two towers, and a watchman's lodge have survived. Through the efforts of monks and parishioners, the bell tower was restored, and in 2007, a renewed cross was placed on it. In 2002, a large wooden cross was erected at the site of the destroyed cemetery in memory of those buried there. There is hope that the church will be revived with God's help.
