Struve Geodetic Arc

The Struve Arc is a chain of survey stations stretching over 2,820 km which was built to determine the exact size and shape of the planet.  The project was initiated by astronomer and scientist Friedrich Georg Wilhelm Struve.

The measurements were taken on the territory of 10 countries — Norway, Sweden, Finland, Russia, Estonia, Latvia, Lithuania, Belarus, Ukraine and Moldova. The results were proved to be very reliable. Only 34 out of 265 stations have been preserved, with 19 points located in Belarus. Archaelogical digs revealed Struve stations in Osovnitsy, Schekotsk, Liaskovichi, Lopaty, Tiupishki, Dokudovo, Ivatsevichi, Belin and Bezdzezh. The Struve Arc was included in the UNESCO World Heritage List in 2005.
