Struve Geodetic Arc | Finland

Postcard

The Struve Geodetic Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through ten countries and over 2,820 km. 

This helped to calculate the exact size and shape of the planet and marked an important step in the development of earth sciences and topographic mapping. Aavasaksa is one of the six measuring points that are located in Finland.

 

The Struve is on the list of UNESCO World Heritage sites since 2005.
