Aiste has just explained to me that
this house of worship was built in 1891-1893.
It was meant for the Kaunas stronghold soldiers,
as a representational building for the Kaunas Army fortress,
expressing luxury and officialdom.

This Neobyzantine style house of prayer was consecrated in 1895
giving it the Russian Orthodox title of St. Peter and St. Paul Cathedral.
Kaunas residents simply call it the "soboras" (Russian Orthodox Cathedral).
Once the Sobor was finished, the New Kaunas centre was complete as a city of a military fortress.
During World War I, mass was held here for the Evangelical German Army soldiers.
In 1919 the Sobor was handed over to the Kaunas military garrison and named St. Michael the Archangel.
After World War II a parish was established in the Sobor
and it ceased to be the military's centre of worship.
A decade ago, the Sobor was appointed to the Lithuanian Army's Kaunas garrison's use,
and a parish was established.
