The Church of the Intercession of the Virgin Mary in the village of Pokrovsk on the Siti, known since the 16th century and located at the lower reaches of the Siti River, is the closest to the Mologa after the vanished churches of Breytovo. This village was the center of the Pokrov-Sit volost, known as the "land of sicarers."

It is believed that the church was founded in 1808. However, its construction likely occurred in two stages with a possible significant time gap between them. This may mean that the building of the church took a long time and spanned two periods of Russian architecture.

Architectural elements such as rusticated pilasters and the surrounds of the apse and main part of the church date back to the Baroque style. At the same time, the decorative arches under the roof and the faceted drum finishes have an archaic appearance typical of the turn of the 17th-18th centuries. The bell tower, set on a base of massive granite blocks, is adorned with Corinthian columns and richly decorated, while maintaining its monumentality and upward aspiration. The refectory, like the bell tower, features restrained decor, but its length disrupts the overall proportions of the structure. This may be related to the fact that the bell tower was built separately and then connected to the church through the extension of the refectory. Such architectural solutions are also found in other churches of the Mologa, such as in Stary Nekozy and Maryino on the Ild River. The bell tower and domes of the Pokrovsky church are visible from afar from all outskirts of the Pokrov-Sit volost, and from its tiers, there is a complete view of the surroundings of the "land of sicarers."
