Struve Arc Võivere Point

One point of the Struve Geodetic Arc, inscribed on the UNESCO World Heritage List, lies in Lääne-Viru County, in a garden next to Võivere Windmill, marked by a limestone foundation.

In 1827, under the guidance of Friedrich Georg Wilhelm Struve, the Simuna–Võivere baseline was measured. Measuring the baseline was part of the meridian arc measurements carried out between 1816 and 1855, aimed at determining the size and shape of the Earth.

Since the summer of 2020, an exhibition has been open on three floors of the windmill next to the Võivere Point, telling the story of the measurement of the Struve Geodetic Arc. Here you can learn how the dimensions of the Earth were determined nearly 200 years ago and why this extraordinary scientific achievement deserves a place on the UNESCO World Heritage List.

Come and discover Võivere Windmill, step onto the paths of the history of science, and become part of the exciting story of UNESCO World Heritage!
