During the 19th century scientists wanted to establish the precise shape of the Earth. A so-called Struve Chain with a number of measuring towers was created stretching from the Black Sea up until the Arctic Ocean. Oravivuori Triangulation Tower is one of the six points of the chain located in Finland. In addition to its scientific importance, this place has some incredible views.
