Simuna is one of the measurement points of the Struve Geodetic Arc inscribed on the UNESCO World Heritage List.
In 1827, under the guidance of the famous astronomer and geodesist Friedrich Georg Wilhelm Struve, they measured the baseline between Simuna and Võivere. This was part of a grand scientific undertaking carried out between 1816 and 1855 to determine the exact size and shape of the Earth. The exceptional precision and scope of the measurements of that time marked an important breakthrough in the history of geodesy.
The Simuna measurement point is marked by a monument erected in 1849 that commemorates a scientific achievement from nearly two centuries ago.
In Estonia, the UNESCO World Heritage objects of the Struve Geodetic Arc also include the Võivere measurement point and Tartu Observatory.
