On the site of the former village, there is now a large clearing with a gentle slope to the south. Here, one can see the ruins of several houses and remnants of a street stretching from west to east, which previously organized the village's layout. On the western outskirts, surrounded by trees, stands the Nicholas Chapel. It is enclosed by an old stone fence, and to the east and south, there are several old graves.

The Nicholas Chapel includes the main prayer room, a vestibule, and a log structure topped with a bell tower. All parts of the chapel are connected into a single elongated rectangular volume covered by a common roof. The entrance is located on the northern side and leads into the vestibule. Among the preserved details, the west side's roof overhang, carved gables, bell tower columns, and underpinnings stand out. The chapel is in a state of emergency: the main log structure has severely rotted due to roof leaks, and the roof and ceiling have collapsed. The bell tower has survived better, although it has tilted slightly, but its structures remain sturdy.

During the inspection, architectural measurements of the chapel were taken, and part of the debris in the prayer room was cleared. The architecture of the Nicholas Chapel seems typical for Karelia at first glance, but upon closer examination, a complex construction history and unique features are revealed. The entrance to the chapel is located on the northern side through the vestibule, from where two openings lead into the prayer room and the bell tower. This layout resembles a residential house with a utility area. The orientation of the entrance to the north is explained by the fact that the main village street ran on this side.

Architect E.V. Vakhrameev inspected the chapel in 1988 when it was not yet so damaged. He made a schematic measurement of the plan and a brief description, noting that there was previously a wall between the vestibule and the main room, and their coverings were of different heights. During the repair and extension of the bell tower, the log structure above the vestibule was aligned with the main room.

Although the covering structures are almost destroyed, traces of reconstructions can be seen on the remaining log structure, revealing the construction history. The reconstruction of the original appearance shows an unusual building with low dark vestibules and a prayer room with a single southern window. The graphic reconstruction includes details corresponding to the archaic proportions of the log structure, allowing the chapel to be dated to the 17th century. This can be confirmed by dendrochronological analysis.

The second stage of construction combined the prayer room and vestibule, adding new vestibules and a bell tower. Insurance assessments from 1910 indicate that the chapel was built in 1820, but this date likely refers to the reconstruction. In the late 19th and early 20th centuries, updates were made, but the architectural changes were minor.

The wall cladding from the 19th century was usually painted, and the Nicholas Chapel has well-preserved paintwork, allowing for the reconstruction of the color scheme. The architecture and history of the chapel require further study.

In the summer of 2018, an expedition led by Pavel Smirnov took place in Yalgandselga. A conservation canopy was installed, and roofing was laid on the bell tower. These measures will prevent further destruction and allow for more comprehensive preservation work on the chapel in the future.
