Siberian Baroque is an architectural style common for ambitious structures in 18th-century Siberia, where 115 stone churches in Siberia were recorded in 1803, most of which were built in this provincial variant of the Russian Baroque, influenced by the Ukrainian Baroque and in some cases even incorporating lamaist motifs. Most of the buildings were preserved in Irkutsk, Tobolsk and Tomsk. An original interior of a Siberian Baroque structure survives only in the Feast of the Cross Church in Irkutsk.
