The stone church in the village of Korovino, which was previously part of the Biryuchensky district, was built in 1800. The John the Theologian Church was affiliated with the George Church in the village of Afonyevka. Thanks to the active protests of local residents, the church was not officially closed during the Soviet period, and services continued to be held there. The church is a monument of architecture.

It is unknown who exactly oversaw the construction of the church, but the quality and evenness of the masonry indicate the involvement of professional workers, which in turn suggests support from high-ranking sponsors.

Architecturally, the building is designed in the classical baroque style, representing a proper cross-shaped structure with an octagonal drum, on which rises a spherical faceted dome topped with a hand-crafted wrought iron cross. The bell tower of the church has three tiers with large arched window openings adorned with masonry. The interior decoration, including paintings and frescoes, was lost during the Soviet era when the building was used for economic purposes. Some locals mention the existence of secret passages in the building's cellars, but given the age of the structure, their preservation is questionable.

Currently, the building is in satisfactory condition, and local residents maintain it and restore it as much as they can. Services are held regularly.
