The village of Demyanskoye, located on the Irtysh River in the northern part of the Tyumen region, has a history of over 370 years. In Siberia, the construction of Orthodox churches began with the establishment of settlements, and Demyanskoye was no exception. The peasants decided that the church should be sturdy, beautiful, and made of stone. The Church in honor of the Assumption of the Mother of God in the Tobolsk district of the village of Demyanskoye was built in 1831 thanks to the efforts of the parishioners, following a plan drawn up in 1800.

According to the clerical records, the church was made of stone, two-storied, with a bell tower of the same height, surrounded by a wooden fence. Inside the churchyard, there was a watchman's lodge. The church had three altars: on the upper floor in honor of the Assumption of the Mother of God, on the lower floor in honor of Saint Nicholas the Wonderworker, and in the chapel on the first floor, on the northern side, in honor of Alexius, the Man of God.

Before the revolution, the church housed a particularly revered icon of Alexius, the Man of God, to which many people flocked on March 17. There was a chapel at the parish cemetery in the name of Lazarus the Four-Days Dead.

In 1936, the destruction of the church began. The MTS was placed within its walls, then a state farm garage was arranged on the first floor, and a club on the second.

In 1996, after the closure of the state farm, parishioners, mostly pensioners, began to restore the ruined church by their own efforts. Gradually, with God's help, it began to regain its former appearance. The first parishioners recall that they did not expect such success in restoring the Assumption Church.

In 1997, Bishop Dmitry of Tobolsk and Tyumen, along with teachers and students from the Tobolsk Theological Seminary, held a clean-up day to clear the church, met with residents, and gave a concert of spiritual hymns to remind everyone of the importance of restoring the church.

Currently, the first floor of the church has been restored, where services are held. The second floor requires conservation to preserve at least its current state. However, this is beyond the capabilities of the small rural community, and significant financial investments are needed to complete the restoration.
