Strūves meridiāna loka ģeodēziskais punkts Kreutzburg

The Strūves meridiāna loka ģeodēziskais punkts Kreutzburg, situated in Jēkabpils, Latvia, stands as a testament to scientific exploration and discovery. As part of the Struve Geodetic Arc, a UNESCO World Heritage Site, this point played a vital role in 19th-century efforts to accurately measure the Earth. The arc itself is a chain of survey triangulations that stretches from Hammerfest in Norway to the Black Sea. In the 19th century, Friedrich Georg Wilhelm Struve initiated the Struve Geodetic Arc to ascertain if latitudes remained constant and held the same value across vast distances. The Kreutzburg point, used for both geodetic and astronomical observations, marks one of the key locations in this ambitious scientific endeavor. These measurements contributed significantly to cartography and navigation, revolutionizing the understanding of our planet. Visiting the Kreutzburg point offers a unique opportunity to connect with the history of science and appreciate the ingenuity of the scientists involved. The site provides informative plaques that detail the significance of the geodetic measurements and their impact on our understanding of the Earth. The peaceful setting allows for contemplation and appreciation of both the natural beauty and human achievement.
