Estonian Post has also issued a joined two stamp souvenir sheet marking Struve’s Geodetic Arc on May 6, 2011. The sheet, shown below depicts contains two 0.58 eur stamps. The upper stamp shows an image of Struve, the lower stamp shows the Tartu Observatory. A map of the complete triangulation route is shown in the background. Tabs exist on each side of the two stamps, and the top and bottom. Historical surveying instruments are shown in the side tabs. The background map is shown on both the top and bottom tabs. Corner tabs display the Estonian Post logo mark. The original arc consisted of 258 main triangles and 265 main station points. Thirty-four of the original station points today survive, and three of them are situated in Estonia, one in the Tartu Observatory and two in Simuna in the West-Viru County. Since 2005 the Struve Geodetic Arc is a UNESCO world heritage site.
