The village of Pupkovo, located in the Gorodetsky district, was liquidated in 1965. One of its architectural monuments is the Transfiguration Church, built in 1812. The book "Saint Blessed Sergius and the Nizhny Novgorod Land" mentions that there was a stone church dedicated to the Transfiguration of the Lord, with an altar in honor of Saint Sergius of Radonezh. The church was erected with the funds of parishioners, and the sound of its bells resonated through the surrounding forests. The staff included a priest and a psalmist. Before the revolution, the parish included, in addition to the Pupkovo area, nineteen other villages. Pupkovo, located on the road, was a small settlement with seven households, including the homes of clergy.

The Transfiguration Church was adorned with ancient icons in carved kiosks. In the warm Sergiev chapel, a five-tiered iconostasis contained carved icons, except for the icon of Sergius of Radonezh, which was traditionally painted. Above the royal gates were carved icons of "The Baptism of the Lord" and "The Descent of the Holy Spirit." The iconostasis also included carved images from the life of Saint John the Baptist. The names of the masters who created this iconostasis have not survived, but it is known that it was donated to the church and likely belonged to another church before. The Transfiguration Church was closed in 1938. In 1965, the village of Pupkovo was liquidated, and the church remained the only witness to the lives of people in this place. Subsequently, many peasant settlements in the area were destroyed and disappeared. Today, the dilapidated church stands in the forest on the road between Gorodets and Kovernino, next to it is an abandoned cemetery, the fence of which is also in ruins.
