The Nicholas Chapel, also known as the Ilyin Frola and Lavra, was built in 1731. The names of the architect, builders, and client are unknown. According to archival data, the chapel in the village of Vadyb was restored in 1731 by the order of Bishop Lavrenty of Veliky Ustyug and Totma, at the request of local residents. Services were held there not only on St. Nicholas Day but also on Ilyin Day and on the day of Frola and Lavra. In the 1930s, the chapel was closed and used as a fertilizer storage until the early 1970s.

It is presumed that in the 13th century a bell tower was added to the chapel, replacing the original porch. In the 19th century, the building was sheathed with boards, and the roof of the main square, previously gabled, was replaced with a dome-shaped one covered with iron. The roof of the octagon was also changed, with a framed octagon topped with a small iron-clad dome and a metal cross. The windows in the chapel and the narthex were enlarged in height, and new boxes were inserted instead of the frames. Inside, the passage from the narthex to the chapel was widened.

In the 19th century, the upper part of the bell tower was destroyed, starting from the ringing tier, as well as the porch in front of the western entrance. The filling of the window boxes was lost, and the stairs to the upper tiers of the bell tower were destroyed. All decorative interior furnishings, including the iconostasis, were destroyed during the period when the chapel was used as a storage facility. The Nicholas Church of 1731 is located in the center of the village of Vadyb. In plan, at the window level, its log structure forms two rectangles. One of them is elongated from east to west and is divided into two parts: the chapel and the narthex dining area. The other rectangle, more precisely a square, adjoins the first from the west and is formed by the log structure of the bell tower. The porch in front of the entrance has not survived. On the western wall of the bell tower, only traces of the beams of the gabled roof remain. The volumetric composition of the chapel developed along two verticals. Previously, the highest part was the bell tower, a type of octagon on a square with an open ringing tier. Now the upper part of the structure is missing, so the exact design of the covering is unknown. The second vertical, the square of the chapel, stands out in height and shape of completion. It rises above the ridge of the gabled roof of the narthex-dining area by several crowns, forming a cornice over each wall. The cornices support the overhangs of the four-pitched covering, transitioning to a dome shape closer to the center. Above the dome rises a hewn octagon. On its octagonal covering is another framed octagon, serving as the base for a small dome with a metal cross. The original covering of the square was shingle, gabled, similar to that of the octagon. Above it rose a drum and a dome. The existing framed octagon was likely constructed during the sheathing of the chapel's log structure. The building is set on stones without a foundation, hewn "in the oblo" with a remainder, except for the octagon above the chapel, which is hewn "in the paw." The rooms of the chapel and the narthex-dining area are located on a high podium, accessed by a staircase inside the bell tower. Currently, they are empty. The ceiling in the chapel is flat, supported by matrix beams. Both rooms are illuminated by six windows, cut into the northern and southern walls, two in the chapel and one in the narthex. Only fragments of the iconostasis have survived. The Nicholas Chapel, an architecturally expressive structure, is the only vertical feature in the monotonous development of the village.

This is one of the few monuments of wooden architecture from such an early time that have survived in the territory of the Komi ASSR. In its original form, the volumetric-planning composition of the chapel was cubic.
