Helsinki was established as a trading town by King Gustav I of Sweden in 1550 as the town of Helsingfors, which he intended to be a rival to the Hanseatic city of Reval (today known as Tallinn). Little came of the plans as Helsinki remained a tiny town plagued by poverty, wars, and diseases. The plague of 1710 killed the greater part of the inhabitants of Helsinki. The construction of the naval fortress Sveaborg (In Finnish Viapori, today also Suomenlinna) in the 18th century helped improve Helsinki's status, but it was not until Russia defeated Sweden in the Finnish War and annexed Finland as the autonomous Grand Duchy of Finland in 1809 that the town began to develop into a substantial city. During the war, Russians besieged the Sveaborg fortress, and about one quarter of the town was destroyed in an 1808 fire.

Another major historical museum is the Helsinki City Museum, which introduces visitors to Helsinki's 500-year history. The University of Helsinki also has many significant museums, including the Helsinki University Museum "Arppeanum" and the Finnish Museum of Natural History.
