The Finland-Sweden Border is a natural boundary that separates the two Nordic countries of Finland and Sweden. It stretches approximately 1,340 kilometers (830 miles) from the northern region near Kilpisjärvi in Finland to the southern area near Haparanda in Sweden. The border is characterized by forests, lakes, and rivers, reflecting the rich natural landscapes of both countries. This border is one of the longest in Europe and has been largely peaceful throughout history. It was officially established in the 1809 Treaty of Fredrikshamn, which resulted in Finland becoming a part of the Russian Empire while Sweden retained its territory. Today, the border facilitates trade and travel between the two nations, promoting cooperation and cultural exchange.
