Сайменский канал
In the course of the 19th century, the town developed as the center of administration and trade for the eastern part of Finland. The inauguration of the Saimaa Canal in 1856 benefited the local economy as it opened the vast waterways of Eastern Finland to the sea. Vyborg was never a major industrial center and lacked large production facilities, but due to its location it served as a focal point of transports of all industries on the Karelian Isthmus, Ladoga Karelia, and southeastern Finland.
