The first wooden Trinity church was built in 1879, but it remained a subsidiary of the Annunciation church in the village of Shestakova, whose parish included the village of Vagina, located across the river. No information about the appearance of this church has survived. Architect M. V. Druzhinin designated the site for construction, and he likely developed the project or adapted one of the standard designs popular at the time for rural buildings.

A separate parish was formed only in 1888. At that time, it included 160 households with a population of over 1500 people. On September 1, 1887, a primary zemstvo school opened in the village, for which the church clergy provided a two-story wooden house free of charge. Later, a separate building was constructed for the school, designed to accommodate 20 boys and 10 girls.

By the early 20th century, there was a need for the construction of a new stone church. Work was funded by parishioners, but due to a lack of money, construction was delayed. The situation improved after the appointment of priest M. S. Yelabuzhsky as the rector, who was able to organize additional collections and attract donations from wealthy residents of Slobodskoy and Vyatka. The church was consecrated on the eve of 1912. In addition to the main Trinity altar, there was an altar in the name of the Uncreated Image of the Savior.

In the first year after the consecration of the new stone church, the number of parishioners exceeded 2200, and the parish included 41 settlements. According to data from 1916, there were 3 households of church servants with 14 residents, 29 peasant households with a population of over 160 people, a zemstvo one-class school, a volost administration, and a medical station. The liquidation of the village occurred in the 1970s as part of the program to consolidate collective farms.

Vagina is known for being the birthplace of the famous entrepreneur and philanthropist Xenophon Alekseyevich Anfilatov in the early 1760s, born into the family of a serf peasant A. I. Anfilatov. He was the first of the Russian merchants to establish direct trade relations with the USA and founded the first private bank in the Russian province in Slobodskoy.

The Trinity Church, standing out among local monuments, attracts with its historical and aesthetic spirit and the possibility of overcoming difficulties to become acquainted with its architectural features.

The church is a compact four-pillar cross-domed building of a central type. Its silhouette, despite the loss of some height elements, is distinguished by the dominating volume of the light drum with a faceted dome and gable finishes of the facades. To the west, the composition is complemented by the lower tier of the bell tower and the refectory-transition. The architectural and decorative forms lean towards the Russian-Byzantine style. The brick walls, originally unadorned, retain traces of later whitewashing. Inside, the walls and vaults were plastered, whitewashed, and decorated with stucco ornamentation.

The author of the project is not established, but the facade style, characteristic of the early 20th century, points to I. A. Charushin. A similar church, whose authorship is confirmed, has survived in the village of Zaev.

The church plan represents a large square with trapezoidal corners, forming an equilateral Greek cross. Massive pylons support the drum, which externally has the shape of a dodecagon. The interior is rich with repeating sections, limited by arches and vaults. A two-tiered solea with choirs and a three-tiered frame of the iconostasis with fragments of carving have been preserved. Three doorways are located along the diagonals of the plan. An octagonal vestibule under the bell tower is complemented by rectangular rooms. The head of the church, the upper tiers of the bell tower, and the porch have been lost.

The facade decor, although corresponding to the overall style of the monument, is eclectic. The walls of the drum are treated with rustication, imitating Byzantine masonry, and kokoshniks of complex profile. The upper part of the walls is decorated with a cornice. The main facades are pierced with large windows with arched lintels. The central openings are highlighted by height and width. The cornice slopes of the gables are supported by arcature bands, and the artistic treatment of these fragments is executed most expressively.
