The Struve Geodetic Arc - RUSSIA - UNESCO #1187
This is my 666th card in the blog (the number of the beast) and it couldn't be a better pick... the Struve Arc is the beast of the UNESCO WHS postcard collectors, because it stretches along ten countries. This is my 2nd card from this site, hoping that one day I can collect the other 8. Thank you very much Anastasia for this double swap and for the amazing Sochi 2014 stamps you used. This postcard took 10 days to arrive!
The Struve Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through 10 countries and over 2,820 km. These are points of a survey, carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhelm Struve, which represented the first accurate measuring of a long segment of a meridian.
