“Yes, the bow is invisible to the eye, it can only be imagined on the globe. But it deserved global recognition because it has set the exact parameters of our planet and allowed us to create accurate maps” explains 81 year old Pranciškus Motuzas, who worked as a surveyor in Rokiškis.

The Struve Geodetic Arc is a unique example of scientific development, cooperation between scientists from different countries, as well as government cooperation in the field of science, stretching over 2,820 km from Hammerfest (Norway) to the Black Sea and crossing 10 countries. The Struve Geodetic Arc has been inscribed on the World Heritage list in 2005.

Friedrich Georg Wilhelm Struve and colleagues began measuring the geodetic arc in several places. One of first measuring place is in Pandėlys in Rokiškis district. Work here began exactly 200 years ago in 1820. Then he chose another point – a small village of Jokšiai in Kupiškis district, on a flat but in the high place, so that trees and buildings would not block the view.

Then in Pandėlys and Jokšiai scientists built wooden towers, called majakai  (in Lithuanian sign) which height was similar to Rokiškis church. Majakai were needed to workers so that they could lift the gadget to the top of wooden towers. Then they had to choose another – the third point. Thus, near Panemunėlis the third point of this triangle, which consisted of Pandėlys, Jokšiai and Gireišiai, appeared.
