The church in the name of St. Olga, the Equal-to-the-Apostles princess, was built in 1897-1898 in the village of Olgino, during the construction of a railway section between the Krasnoyarsk-Right and Klyukvennaya stations. Funding for the construction came from parishioners and from the fund named after Emperor Alexander III, while the project was developed by the Ministry of Railways. The construction was overseen by N.P. Mezheninov, the chief of works for the construction of the Middle Siberian Railway, with engineers M. Yastrebov, N. Nekhoroshev, L. Blumenau, and M. Tsigler-fon-Shafhausen participating in the process.

The wooden church building has a cross-shaped plan: the main square part is surrounded by side arms and a rectangular apse, the dimensions of which match those of the arms. A refectory, oriented latitudinally, is adjoined from the west by a porch with a staircase. The main volume of the building represents a "wide octagon on a square base," topped with a tent roof and a large dome. The transition from the square base to the octagon on the facades is marked by single-pitched triangular roofs. Each face of the octagon features a triangular gable and two narrow vertical windows. The neck of the temple's dome at the bottom is adorned with a "ring" of triangular zakomars. The bell tower is located under a gable roof and has an opening. In the southern part of the porch, there is a two-flight staircase.

The walls of the building are made from large logs with remnants. The lower tier of the church has a monumental log surface, contrasting with the boarded walls of the temple volume. The facades of the northern and southern arms are pierced by a triple window and have no entrances. The triple window is framed by a lintel, the vertical elements of which extend upwards and overlap a frieze made of vertically laid boards with a intricately cut bottom. The bottom of the lintel frame is decorated with three "drops." The walls of the northern and southern facades of the arms are topped with triangular pediments, adorned with a hanging structure of four carved weights, united by a horizontal beam. The tympanum of the pediment is pierced by a pair of shaped embrasures. The cornice of the pediment is decorated with carved undercuts.

The western facade has a double-leaf door opening with doors covered in sheet metal. The upper part of the facade is pierced by a shaped opening in the form of a Latin cross. Rectangular window openings of the bell tower on the side facades are accentuated by triangular pediments, embedded in the gable roof. Each pediment is decorated with a "hanging weight" with a horizontal beam. Rectangular windows are framed by simple lintels, and the windowsill has a semicircular projection, designed like an "orange slice." Metal grilles are inserted into the windows. The porch is supported by four columns, decorated with shaped brackets. The roof of the porch has a complex shape: a triangular pediment with its own gable roof is embedded in the gable roof from the west. The cornices of the roof are adorned with carved undercuts. The interior of the temple is richly decorated with ornamental carvings, especially in the upper part of the building.

In the side chapels, fragments of carved wooden iconostases have been preserved. The two-tier altar barrier of the chapels consists of a three-part frame with a triangular gable in the center. The structure of the iconostasis rests on pilasters: the upper ones are paneled, the lower ones are without panels. The capitals of the pilasters in the upper tier are decorated with an equal-armed cross. The gable is adorned with a carved band of wavy pattern. The coloring of the iconostasis imitates marble. The surfaces of the "plinths" are decorated with panels featuring cross-shaped elements. The roof of the building is metal. The dimensions of the building are 23.02 x 17.20 m.

The cross on the temple dome, elements of the interior decoration, and part of the facade decor have been lost.

This is a well-preserved example of a wooden Orthodox church from the late 19th century in the "Russian style," built according to a standard project.
