This church was officially known as the Church of the Holy Apostles Peter and Paul attached to the 13th Leib-Grenadier His Majesty’s Erivan Regiment.
It served as the regimental church of the Russian Imperial Army, which was stationed in Manglisi.
The construction of the church was financed by funds allocated by Emperor Alexander II, as well as by donations from military units and private individuals, a practice typical of army churches of the period.
According to surviving records, 22,360 rubles were donated by units of the Caucasus Military District and private benefactors, with an additional 10,000 rubles provided from the state treasury.
The church was built between 1872 and 1897 and was consecrated in 1897, a bell tower was added in 1907.
Architecturally, the building was designed in the Neo-Byzantine style, which was widely used in the construction of regimental and military churches in the late XIX century.
Unfortunately, the cathedral of the Erivan Regiment has not survived to the present day.
Although no direct documentary evidence of its demolition has been identified, the complete absence of any ruins suggests the deliberate destruction of the building rather than its gradual loss through neglect.
The most proobably period of destruction lies between 1924 and 1937, with the early to mid 1930s being the most realistic.
This timeframe coincides with the peak of the anti-religious campaign in the USSR and corresponds to the fate of a number of similar regimental churches in Tiflis, Kutaisi, and Akhalkalaki.
