Omsk is a city and the administrative center of Omsk Oblast, Russia, located in southwestern Siberia 2,236 kilometers (1,389 mi) from Moscow. With a population of 1,154,116, it is Russia's second-largest city east of the Ural Mountains after Novosibirsk, and seventh by size nationally. Omsk acts as an essential transport node, serving as a train station for Trans-Siberian Railway and as a staging post for the Irtysh River.
During the Imperial
era, Omsk used to be the seat of the Governor General of Western
Siberia and, later, of the Governor General of the Steppes. For a brief
period during the Russian Civil War in 1918–1920, it served as the capital of the anti-Bolshevik Russian State and held the imperial gold reserves.
Omsk is the administrative center of the Siberian Cossack Host.
It also serves as the see of the bishop of Omsk and Tara, as well as the administrative seat of the Imam of Siberia.The architectural centerpiece of the city is an ensemble of buildings
along Lyubinsky Avenue/Lenina Street, anchored by the former Gostiny Dvor,
and flanked by two chapels. The area is an eclectic mix of
architectural styles, dominated by Art-Nouveau, Neoclassical and Second
Closer to the confluence of the Om and the Irtysh are the few
surviving sombre buildings of the 18th-century fortress.
The largest and
most opulent church in the city is the Dormition Cathedral, a five-domed edifice in the Russian Revival style, consecrated in 1896, demolished by the Soviets, and restored in the early first decade of the 21st century.
Another area of interest is Nikolsky Avenue-Krasnykh Zor Street,
where a line of merchants' wooden houses still stands. The street leads
to the Neoclassical cathedral of St. Nicholas, which was commissioned by the Cossacks, designed by Vasily Stasov and consecrated in 1840. It contains various relics of the Siberian Cossacks.
