Struve chain

In Korpilahti, at the top of Oravivuori, lies one of Finland's six points in the Struve chain. This is a triangulation chain extending from the Black Sea to the Arctic Ocean that was used in the 19th century to establish the shape of the earth. On this spot a triangulation tower has been erected to commemorate the importance of the Oravavuori (or Puolakka) measuring station to the mapping of Finland. Struve's chain gained inclusion on the UNESCO world heritage list in 2005. Thank you dear Ella for this interesting card.
