The Transfiguration Cathedral Church was the main worship place of the Pustozerskaya volost throughout history. All the main services and holidays were held there: Christmas, Epiphany, Easter, etc. The exact date of its construction is unknown, but the first mention of the Transfiguration Church we find in the Tsar Ivan IV letter of grant given to the Kanin and Timan Nenets in 1545. The temple was made of wood. It was demolished and rebuilt three times for several centuries.
The last version of the Transfiguration Church was erected in 1837. It was built of larch on a stone foundation. Unlike traditional wooden northern churches which were often cramped and poorly lit the Pustozersk temple was spacious and light. The church was lit up by twenty large and small windows.
The interior decoration of the church was rich and consisted of a carved iconostasis, icons in silver rizas, ancient encrusted altar crosses, silver utensils. Old printed liturgical books were kept in the sacristy of the church. Metal bars were placed on the windows to protect church property. Eighteen of twenty windows had iron lattices.
Initially, an elementary school was located in the Transfiguration Church in the 30s of the XX century and then a boarding house for the elderly so the iron lattices were no longer needed. Some of them were installed on the windows of a town fishery cooperative store in the village of Ustye. They were dismantled during the store renovation in the 90s of the XX century. The lattice was picked up by Durkina Lyudmila Ivanovna and handed over to the funds of the Pustozersk Museum-Reserve.
