The cathedral was funded through donations from the Siberian Cossack Host and local residents.
It originally held the relics of St. Nicholas the Miracle-Worker, sent from St. Petersburg.
The building was designed by architect Vasily Stasov, a prominent figure in the Russian Empire's classical architecture.
During the Soviet era, the building's interior frescoes were largely destroyed or painted over before being recovered during restoration.
It survived the massive anti-religious demolition campaigns of the 1930s that claimed many other Omsk churches.
The cathedral once served as the burial place for several prominent Siberian military figures.
St. Nicholas Cossack Cathedral is a historic stone place of worship built between 1833 and 1840 to serve the Siberian Cossack Host. The structure follows the late Russian Classicism architectural style, featuring a distinctive five-domed design. Historically, it served as the primary cathedral for the Omsk Cossacks and houses significant religious relics, including the banner of the Yermak Cossack Host. During the Soviet period, the cathedral was repurposed into a cinema and later an exhibition hall, undergoing extensive restoration in the 1990s to return it to its original religious function. It is situated in the historic center of Omsk along the city's main thoroughfare. The exterior walls are characterized by a soft yellow color palette typical of 19th-century Siberian administrative and religious architecture.
