 However, the question of "stylistic revival" in Finland has another important cultural-political aspect, the presence of the Russian Empire through the building of Russian Orthodox churches in the second half of the 19th century - though what is regarded as the initiation of the deliberate politico-cultural policy of the Russification of Finland didn't take place until the reign of Czar Nicholas II, from 1899 onward.Initially, just as in the Russian capital, St. Petersburg, the Russian Orthodox churches were initially designed in the prevailing neoclassical style; however, the latter half of the 19th century also saw the emergence of a Russian Revival architecture and Byzantine Revival architecture - part of the interest in Russia as in Finland and elsewhere in Europe of exploring nationalism - with distinct "onion domes", tented roofs and rich decoration.Several such churches were built in Finland, the vast majority in the eastern half of the country, with notable examples in Tampere, Kuopio, Viinijärvi and Kouvola.
