In the dense forests of Belebei, a semi-splintered village emerged. The owners of three copper smelting plants north of Belebei, Verkhnetroitskoye, Nizhnietroitskoye, and Usen-Ivanovskoye, were the industrialists Osokins, who provided significant financial support to the young poet G.R. Derzhavin. These plants essentially formed one enterprise, as they were not independent in ore extraction and copper smelting.

The Verkhnetroitskoye plant was founded in 1752 by Ivan Gavrilovich Osokin, who also built a stone church between 1753 and 1759. The main altar of the church in honor of the Holy Trinity was consecrated in 1759, as confirmed by the church deed signed by Bishop Gabriel of Kazan and Sviyazhsk. From the 1760s, the plants passed to the founder's nephew, Ivan Petrovich Osokin, who likely completed the church's arrangements. In 1773-1774, the plants were destroyed by Pugachev's followers but were restored by 1777.

The architecture of the church is typical of the early Romanov period: a two-light cubic base supports a high Vologda octagon with slender half-columns. The tall tent-like bell tower appears to be a century late. The church was originally adorned with stucco decor, and the lower part was rusticated. The added chapels and porches distorted the original forms of the church, submerging the bell tower in the lower floor. The church is one of the oldest in the Ufa diocese, alongside the church in the village of Berezovka, and is recognized as an outstanding architectural monument of the 18th century. The Holy Trinity Church is located in a picturesque spot, with a pond on the northern side creating a beautiful view.

In 1837, the Osokins sold the plants to industrialist Dmitry Egorovich Benardaki and disappeared from the historical scene. Around 1850, the church was altered: a northern chapel was added, the facades were replastered, and the stucco decorations were lost. The side altars are dedicated to the Nativity of Christ and St. Martyr Leonid. The floor of the church is laid with stone slabs. To overcome the schism, Benardaki built a wooden Trinity church for the Old Believers in 1855, which stood until 1993. In 1864-1866, the Verkhnetroitskoye plant was abolished. In 1915, Emperor Nicholas II donated a "royal thousand" for the repair of the Trinity church.

In the 1930s, both Trinity churches were closed. An attempt to topple the bell tower of the brick church with a tractor was unsuccessful. The church was used for half a century as a warehouse, forge, mini-power station, garage, and workshops. The roof, windows, doors, floors, and plaster were lost, and cracks appeared in the walls with chipped bricks.

The church was returned to the faithful in 1991 in a dilapidated state. A small cupola with a metal covering and topped with a cross remained on the bell tower, a unique case in the diocese. Restoration work began in 1992, when regular services resumed with the opening of the parish. A two-pitched metal roof was made over the refectory, a breach in the wall of the northern chapel was repaired, windows were restored, and plastering work was completed. Services are held in winter in the northern chapel and in summer in the main church. In 1994, 9 bells were installed, and in 1997, the octagon above the dome.
