The Old Believer Church of Nicholas the Wonderworker, built in Staraya Russa in 1371, is located in a picturesque spot near the old riverbed of the Porusya. Nearby is the residence of the prince's governor and the Trading Square. In the chronicles of that time, it is mentioned as the church "of Nicholas in the city." Originally, it was a small four-pillar temple, typical for that time, measuring 8 by 8 meters with an internal space of 5.6 by 5 meters. The church had one dome and a wide narthex. Brick was mainly used for arches, windows, and vaults, while the walls were made of limestone slabs and shell rock, with wooden ceilings. The iconostasis was adorned with a luxurious image of Nicholas of Myra, the patron of trade. Over time, the temple fell into disrepair, and in the late 18th century, it was restored, preserving its original appearance but making it more durable and beautiful. At that time, the temple became five-domed, and in 1750, a tall bell tower was built nearby. In the early 19th century, the church, like many others, was closed and transferred to the state. In 1931, it became a vegetable storage. During the war, the temple was partially destroyed but was soon restored. Later, part of the local history museum's exhibits were placed here, and the building was used for various needs. In 1990, the church was returned to the Old Believer community, which carried out a major renovation. By 1991, the first service was held here. In 1992, a project was developed to build an additional building between the church and the bell tower, which housed a refectory, narthex, wardrobe, and utility rooms. A fence was installed around the church. The following year, all five domes of the temple and the dome of the bell tower were replaced, covered with copper and fitted with new gilded crosses.
