The history of the Savior Church begins in 1679, when the Itantsy Ostrog was founded on the banks of the Selenga River, at the mouth of the Itantsa, on the site of a former wintering. In 1706, a wooden church of the Savior Not Made by Hands was built near the ostrog, surrounded by 12 households of residents. However, it soon burned down but was restored. By the end of the 18th century, the church had fallen into disrepair, and many new Russian settlements appeared in the Itantsa valley. In March 1787, the Irkutsk Spiritual Consistory issued a decree to erect a new stone Savior Church in the Itantsa valley, choosing a site in Turuntaevo rather than in the village of Ostrozhnoe.

The laying of the church in Turuntaevo took place on June 10, 1791, by order of the Irkutsk Spiritual Consistory. The construction was overseen by master Feodul Yezhakov. Due to the poverty of the local residents, the process dragged on for nearly 30 years and was completed only in 1818. Repair work was carried out in 1829 and 1913. The church had two altars: in the main 'cold' part in the name of the Not Made by Hands image of Christ the Savior and in the 'warm' chapel in honor of St. Nicholas of Myra, consecrated in 1800. The interior was adorned with iconostases with carved details and gilding, ancient icons, and church utensils made of gold and silver. The church also had a rich library.

In 1927, the church was closed by the decision of the village executive committee due to the impossibility of maintaining it and paying taxes. On March 18, 1939, the church was partially destroyed and completely looted; icons, ancient books, and utensils were burned. The faithful were not allowed to take anything from the church. Since 1939, the building was used as an NKVD warehouse, and later it was transferred to the district consumer society. In recent decades, it was not used. In 1991, the district council executive committee approved the 'Revival' program for the restoration of historical and cultural monuments in the Baikal region.

In 1995, an Orthodox community was recreated in Turuntaevo, and on June 13 of the same year, a parish was registered. On December 19, 1999, the altar in honor of St. Nicholas, Archbishop of Myra in Lycia, was opened and consecrated. In April 2000, restoration work began on the Savior Church in Turuntaevo.
