The St. Nicholas Church in the village of Ardon was built in the early 20th century, with its foundation laid in 1901. In 1938, the church was closed, and the priest, Alexey Severinov, was repressed on charges of Trotskyism, with his further fate unknown. The church building was converted into a blacksmith workshop. In 1942, during the German-Fascist occupation, the church reopened and continues to operate to this day.

The church is located on a hill in the center of the village and is a dominant element of its architecture. Built in the early 20th century, it features whitewashed brick walls and log finishes clad in wooden shingles. This is a distinctive rural church of southwestern Bryansk with a concise decor and influences of the Art Nouveau style in its architecture. Its cross-shaped composition resembles the ancient wooden churches of Bryansk. The main cubic volume rises above the rectangular altar, refectory, and side arms, all covered with gabled roofs with pediments. At the top of the church is a hewn octagon with a large faceted onion dome and a cross. Above the western part of the refectory with an entrance porch on two columns rises a massive bell tower with ringing arches, topped with a wooden octagon and a faceted dome roof. The rectangular windows of the church, with simple wooden frames and shutters, resemble those of residential houses. The facades are adorned with simple cornices and moldings that echo the silhouette of triangular pediments. Inside, the central part of the church is connected to the adjacent rooms by wide arched openings, while the western part of the refectory with the staircase to the bell tower is separated. The ceilings are flat and beam-supported. The interior decor dates back to the early 20th century, while the iconostasis with icons is from the late 19th to early 20th century.
