5H6C+7P Lyaskovichi, Belarus
The point is located 600 meters southeast of the settlement of Lyaskovichi in the Ivanovsky district of the Brest region. The center of the site is represented by a granite cube with a hole drilled into it, filled with metal. Nearby stands a memorial sign in the form of a 1.5-meter stele topped with a large sphere, as well as a hollow pyramid. The distance to Brest is 150 km.
The Belarusian part of the chain was constructed by a group of soldiers under the leadership of Lieutenant General Iosif Ivanovich Khodko, a talented Belarusian surveyor, cartographer, and astronomer.
Groups of enthusiasts are actively working today to search for and restore ancient points. In Belarus, the section of the Russo-Scandinavian Arc included 31 points; to date, 22 have been restored. This is the largest number of geodetic points found in any of the 10 countries through which the arc passed.
In the Ivanovsky district of the Brest region, there are 3 points of the Struve Arc: Shchekotsk – the geodetic point "Chekutsck," Lyaskovichi – the point "Leskovichi," and Osovnitsa – the point "Osovnitsa." The cube in Shchekotsk was recently excavated; it was found at a depth of 1 meter, and a measuring cross-shaped mark with the date 1825 is inscribed on the cube itself. There is also a black stele 1.5 meters high, topped with a 100-kilogram sphere simulating the Earth. The contours of Belarus are depicted on this sphere. Similar steles are located at the geodetic points "Leskovichi" and "Osovnitsa."
The Struve Arc, once known as the "Russian" and later the "Russo-Scandinavian Meridian Arc," is one of UNESCO's World Heritage monuments. The arc consists of 265 triangulation points, along which measurements were conducted from 1816 to 1852 that allowed the precise determination of the Earth's size and shape.
The reference points of this triangulation network were marked in various ways on the ground: hollows carved into rocks, iron crosses, stone pyramids, or specially installed obelisks. Often they were marked with sandstone bricks placed at the bottom of a pit; sometimes it was a granite cube with a cavity filled with lead, laid in a pit with cobblestones.
During the 8-year project to include the Struve Arc in the UNESCO list, special search and geodetic work was undertaken in each country to locate the original points. All information from all the countries of the Struve Arc was collected, structured, and standardized.
Not all of the original points were found during the special search and geodetic work carried out in recent years with active cooperation from scientists of the interested countries, and many of them were found to be heavily damaged. Therefore, only the best-preserved points—a total of 34—were included in the World Heritage site.
