In Moldova, there is a monument included in the UNESCO World Heritage list – this is the Struve Arc point at Rud. The monument at this location was unveiled on June 17, 2006. During its surveys across the entire territory of Bessarabia (now Moldova), points were recorded, totaling 27. Currently, only one point remains preserved in the country, located in the village of Rud. It is situated in an apple orchard, 300 meters from the Soroca – Ataki highway.

The Struve Arc, once known as the "Russian" and later the "Russo-Scandinavian Meridian Arc," is one of the UNESCO World Heritage monuments. The Arc consists of 265 triangulation points, where measurements were conducted from 1816 to 1852, enabling the precise determination of the Earth's size and shape.

The reference points of this triangulation network were marked on the terrain in various ways: 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 works were carried out in each country to locate the original points. All information from 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 works conducted 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.
