Primarily used to describe an architectural style evident in Russia from the late 19th century until 1917 that relies on old Russian decoration and spatial constructs. It can be seen in many Old Believer churches built between 1906 and 1917. The neo-Russian style existed before and after the Modern Style, the Russian reaction to Art Nouveau, and is considered a separate movement. Proponents include Ivan Fomin and Ivan Zholtovsky.
