Description

This is one of the four authentic Struve geodetic arc points found in Latvia. The point was surveyed and laid out between 1825 and 1827 by the eminent geodesist Karl Tenner, an associate of Friedrich Georg Wilhelm Struve. Scientists found it in the environment in 2008.
The point is located in the Selonia hills, in the glacier margin formation zone. Once destroyed, it has now been reconstructed and restored, finishing the work by casting the sign in lead.
The Struve geodetic arc points are evidence of the longest and most accurate geodetic survey system of the 19th century, carried out by Friedrich Georg Wilhelm Struve and Karl Tenner. The measurements allowed us to determine the size and shape of our planet, and confirmed Isaac Newton’s theory that the Earth is not exactly spherical, but flattened poleward.
