The Struve Geodetic Arc - UKRAINE - UNESCO #1187

Another card from Ukraine, now with one of the worst nightmares for UNESCO WHS collections in Europe - the Struve Geodetic Arc was a major scientific breakthrough in the early 19th century, but for a postcard collector it's very hard to get all the 10 postcards from 10 different countries and be able to strike this site from the list... well one down, nine to go! Thanks you very much Serggi. This postcard took 15 days to arrive!
UNESCO #1187 - The Struve Geodetic Arc - UKRAINE
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.
