The end point of Struve's Geodetic Arc - the Meridian monument

Share

Struve's Geodetic Arc, named after the Russian astronomer and geodet Friedrich G. W. Struve (1793-1864), was put on UNESCO's world heritage list in 2005. On the basis of measurements made on foot in 1816-1855 it was determined that the earth's radius was 6 378 361 metres, 224 metres more than today's advanced measurement methods have shown to be the case. Struve's Geodetic Arc was measured using a 2822 km triangulation chain from Ismail by the Black Sea to Fuglenes in Hammerfest. The meridian monument here is the northerly end point.
