 An early example, the Suomenlinna church (1854) in the fortress off the coast of Helsinki, was designed by Moscow-based architect Konstantin Thon, the same architect who designed, among other key buildings, the Cathedral of Christ the Saviour, the Grand Kremlin Palace and the Kremlin Armoury in Moscow.The presence of the Orthodox church in the heart of Helsinki was made clear by the placement of the Uspenski Cathedral (1868) on a prominent hill overlooking the city; its architect, Aleksey Gornostayev was one of the pioneers of the Russian Revival architecture, credited with the rebirth of traditional tented roof architecture of northern Russia, which is also a prominent feature in the Uspenski Cathedral.This period also marked the establishment of the first architecture courses in Finland, and in 1879 these began at the Polytechnical Institute in Helsinki, though at first with German or German-educated teachers.
