The Holy Ascension Church in Syktyvkar is the oldest active church in the city. It is located in the former suburb of Kiryv (Kirul), which is now part of the city limits, in a block bordered by the streets Naberezhnaya, Kirova, and Zavodskaya.

The church was built in 1820 as a cemetery church and consecrated on May 8, 1822. Until its closure in 1938, it remained the only active church in Syktyvkar and served as the cathedral church for the bishop of the Renovationist movement in Usty-Sysolsk and Usty-Vym. Restoration began in the early 1990s, which contributed to the revival of parish life. From 1990 to 2004, the Holy Ascension Church served as the cathedral until the construction of the Holy Stephen Cathedral.

In the early 19th century, from 1814 to 1816, at the initiative of the mayor of Usty-Sysolsk, merchant Alexei Ivanovich Sukhanov, and at his expense, the construction of a stone cemetery church began. The church construction permit was issued on July 23, 1811, by the Bishop of Vologda, Eugene. The church was completed in 1820 and consecrated on May 8, 1822. The Ascension Church combined warm and cold churches in one building. The warm church had two altars: the southern altar in the name of St. Nicholas the Wonderworker and the northern altar in the name of St. Alexius, Metropolitan of Moscow; in the cold church, the altar was in the name of the Ascension of the Lord. Next to the church, a three-tiered bell tower was built. A wooden Nicholas church stood next to the new stone church until the fire of 1848.

After the revolution, the status of the church changed. In the early 1920s, it was handed over to the community of believers and became a parish church. In the early 1930s, due to the lack of possibility to expand the cemetery, it was decided to move it to a new location. The townspeople were offered to move the burials themselves, but this was almost not carried out. In 1932, the cemetery was closed as it was surrounded by houses and had no prospects for expansion. Later, the fence was dismantled, stone monuments were removed, and wooden crosses were buried. Many burials were destroyed during the laying of communications and the construction of basements. Among the lost graves, historians believe, was the grave of partisan Domna Kalikova. Over the 140 years of the cemetery's existence, at least 25,000 people were buried there.

Until April 4, 1933, the church belonged to the 'Tikhonites' community, and then it was transferred to the 'Renovationists' community, supporters of the reform of the Russian Orthodox Church. Until its closure in 1938, the church remained the only active church in Syktyvkar and served as the cathedral church for the Renovationist bishop. After the building was confiscated, the church fell into disrepair: it was closed, the cross was removed, and the bell tower was destroyed. For a long time, the building was used as garages, warehouses, and workshops, and at one time, it housed a bread factory.

On March 30, 1971, the church was placed under state protection as an architectural monument. In the 1980s, restoration work began. From 1986 to 1990, the church housed the ethnography department of the Komi Republican Museum of Local Lore.

The religious community of the Russian Orthodox Church in Syktyvkar, registered on March 29, 1989, sought the return of the church to its rightful owner. More than 2,500 people signed a petition for the return of the church building. The editorial office of the newspaper 'Krasnoe Znamya' received over 100 collective letters with similar requests. A public opinion survey showed that the majority of townspeople supported the transfer of the building to the religious community. Based on this and in accordance with the resolution of April 8, 1929, the building was transferred to the community of the Russian Orthodox Church on February 5, 1990.

After the church was returned to the believers, work began on its restoration under the guidance of Father Ioann (Lapko). The head with the cross, the spire on the bell tower, the solea with the pulpit were restored, and an iconostasis made by master Joseph Dolganich was installed. From 1994 to 1996, the walls and vaults of the church were painted by artists V. Piklyar and P. Zakharchuk. The bell tower was not fully restored due to the proximity of the airport.

The Church of the Ascension of Christ is one of the best examples of classicism in the historical architecture of the city. Its feature is the rounding of the corners of the church and refectory, complemented by a semi-circular apse, a spherical dome, and oval window openings of the rotunda.

With the restoration, the parish life of the church revived, which had long been the only one in Syktyvkar. From 1990 to 2004, it served as the cathedral church. Among the church's relics are particles of the relics of Blessed Matrona of Moscow, Saint Luke (Voino-Yasenetsky), icons, and reliquaries with particles of the relics of saints.
