This cultural heritage site represents a chain of astronomical and geodetic survey points that extends across Eastern Europe. The arc was established in the 19th century as part of a major scientific project to measure the meridian and determine the precise shape and size of the Earth. The survey work involved measurements taken from multiple locations spanning considerable distances, with Estonia containing several of the original observation points. These sites are marked by stone monuments and plaques that document this significant scientific endeavor. The heritage value lies in the documentation of early scientific methodology and international scientific cooperation during the 19th century. The arc demonstrates the practical application of astronomical observation for mapping and understanding terrestrial geography across diverse landscapes and political territories.
