The Struve Geodetic Arc is a chain of survey triangulation points that stretch from Hammerfest in Norway all the way to the Black Sea. The imaginary lines go through ten countries and over 2,820 kilometres. Carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhelm Struve, this survey represented the first accurate measuring of a long segment of a meridian, helping establish the exact size and shape of the planet. Sweden has seven measurement points and four of them are on the World Heritage List (on the mountains Tynnyrilaki, Jupukka, Pullinki, and Perävaara). The mountaintop unveils an expansive view.
