The points were set up in a survey by the astronomer Friedrich Georg Wilhelm Struve who first carried out an accurate measurement of a long segment of a meridian – and along with it the size and shape of the Earth. Originally, there were 265 station points. The World Heritage Site includes 34 points in ten countries (North to South: Norway, Sweden, Finland, Russia, Estonia, Latvia, Lithuania, Belarus, Moldova, Ukraine), two of which are in Latvia.
