Cathedral of the Theotokos, Vilnius

The cathedral was built during the reign of the Grand Duke of Lithuania Algirdas for his Orthodox second wife Uliana of Tver in 1346.

[1] It was constructed by Kievan architects with the blessing of Saint Alexius, Metropolitan of Kiev and all Rus', in 1348.

After their deaths, the cathedral was taken over by the Uniate Catholic church in 1609 and was rebuilt in a style typical of the region.

The old cathedral was confiscated and transferred to the Russian Orthodox Church on the initiative of count Mikhail Nikolayevich Muravyov and his brother during the Russification campaign.

The Russian architect Nikolai Chagin was responsible for its reconstruction from 1865 until 1868 in a style imitating medieval Georgian architecture.
