Many Orthodox churches in Finland are small. The few more impressive shrines were built in the 19th century, when Finland was an autonomous Grand Duchy in the Russian Empire, with the Orthodox Christian Emperor as the Grand Duke of Finland. Notable churches in Helsinki from that era are the Uspenski Cathedral (1864) and the Holy Trinity church (1826). The oldest Orthodox church in Finland is the church of Protection of the Theotokos in Lappeenranta from 1782 to 1785.
