UNESCO World Heritage Sites in Estonia

Struve Gedetic arc observatory Tartu University Estonia
The observatory at the University of Tartu, Estonia, where Friedrich Georg Wilhelm von Struve worked, and which became the origin point of the Struve Geodetic Arc.

There are two UNESCO World Heritage sites in Estonia, one encompassing the historic Old Town of Tallinn and the other, the origin point of the Struve Geodetic Arc at the University of Tartu, which memorializes the significant scientific achievement of German-Russian scientist Friedrich Georg Wilhelm von Struve, who was working at the University.

The Struve Geodetic Arc actually is marked in ten countries. It is a chain of survey triangulations, made between 1816 to 1855, that stretches from Hammerfest in Norway to the Black Sea, over 2,820 km (1750 miles,) to establish the exact size and shape of the earth.

The commemorative site at the University of Tartu contains a lot of the instruments von Struve used in his calculations, as well as his telescopes used in his significant work as an astronomer.
