Struve Geodetic Arc

Nestled in the scenic landscape of Finland, Oravivuori is home to a fascinating piece of our planet's scientific history: the Struve Geodetic Arc. Recognized by UNESCO as a World Heritage site in 2005, this arc stands as a testament to the cultural heritage of science and technology. Picture this: a chain of survey triangulation points stretching an impressive 2,820 kilometers from the Arctic Sea all the way to the Black Sea, crossing through ten countries. It was meticulously measured between 1816 and 1855 to help define the size and shape of the Earth.

In Finland, six stations mark this historic arc, with the most renowned being the Puolakka point atop Oravivuori in Korpilahti. This spot is particularly celebrated, not just for its scientific significance, but also for the stunning panoramic views of Lake Päijänne. Imagine standing on a hilltop, surrounded by Finland's breathtaking natural beauty. A triangulation tower proudly stands here, commemorating Oravivuori’s pivotal role in the mapping of Finland.

For those who love a good hike, the journey to the top is an adventure in itself, offering glimpses of local flora and fauna. Once you reach the summit, the view is worth every step. The area is a favorite among locals and tourists alike, perfect for a day of exploration, learning, and relaxation.
