In the first half of the 18th century, a unique stone architectural ensemble was created in Nyrub, unmatched in the region. At the center of the village, on an elevation, stand two stone churches. Between them, on the southern side, was a bell tower, which served as the main architectural dominant of the ensemble. It consisted of a low square base, a tall octagonal pillar, and two octagonal roofs with domes.

Despite its impressive size, the bell tower did not weigh down the ensemble; rather, it added expressiveness to it. Unfortunately, in 1934, the bell tower was dismantled. The earliest structure of the ensemble is the five-domed St. Nicholas Church, built in 1704 and consecrated in 1705.

The architecture of the church is executed in the style of 'Moscow Baroque.' It has a traditional structure: a square cuboid, a refectory, and a five-sided apse are aligned along one axis. Later, a porch with a hanging weight was added to the western side, which was removed during the restoration of the monument in the mid-1950s, as it was deemed inconsistent with the original appearance.

St. Nicholas Church was known for its abundance of Baroque decorations. The entire monument is adorned with stone carvings.

The interior of St. Nicholas Church was also of great interest. Arched openings were made in the walls facing the altar and the refectory. The vaulted ceilings, high window arches in the altar apse and refectory, as well as the slopes of the upper windows in the church, gave the interior a sense of plasticity.

An unusual phenomenon was discovered in St. Nicholas Church: on all four sides of the vault, there are recesses in the shape of eight-pointed crosses, filled with wooden crosses. In the walls of the church, restorers found niches with clay vessels that improved acoustics. Besides the architecture, the church is interesting for its icon of St. Christopher with a dog's head. There is a legend about the builders who erected the church not in the sight of the residents, but at night. They built it without scaffolding and lifts, and it appeared suddenly, as soon as the domes and crosses were installed.
