The Dormition Cathedral (Russian language: Успенский собор) in Omsk is one of the largest churches in Siberia.
Its fanciful design of many shapes and colors utilizes a plethora of elements from the Russian and Byzantine medieval architectural vocabulary.
[1] A revivalist design was commissioned from Ernest Würrich, a fashionable architect based in Saint Petersburg.
The Russian Orthodox Church had the edifice rebuilt to Würrich's original designs in the early 21st century.
[2] The worshippers from all over Siberia come to the church in order to venerate the relics of Bishop Sylvester, a Kolchak supporter who was martyred by the Bolsheviks in 1920.
