Struve Geodetic Arc, Tartu, Estonia (UNESCO WH Site)

http://whc.unesco.org/en/list/1187

The Struve Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through 10 countries and over 2,820 km. These are points of a survey, carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhelm Struve, which represented the first accurate measuring of a long segment of a meridian. This helped to establish the exact size and shape of the planet and marked an important step in the development of earth sciences and topographic mapping. It is an extraordinary example of scientific collaboration among scientists from different countries, and of collaboration between monarchs for a scientific cause. The original arc consisted of 258 main triangles with 265 main station points. The listed site includes 34 of the original station points, with different markings, i.e. a drilled hole in rock, iron cross, cairns, or built obelisks.

Historic Centre (Old Town) of Tallinn, Estonia (UNESCO)

http://whc.unesco.org/en/list/822

 

The origins of Tallinn date back to the 13th century, when a castle was built there by the crusading knights of the Teutonic Order. It developed as a major centre of the Hanseatic League, and its wealth is demonstrated by the opulence of the public buildings (the churches in particular) and the domestic architecture of the merchants' houses, which have survived to a remarkable degree despite the ravages of fire and war in the intervening centuries.

Flag of Estonia

Three equal horizontal bands of blue (top), black, and white; various interpretations are linked to the flag colors; blue represents faith, loyalty, and devotion, while also reminiscent of the sky, sea, and lakes of the country; black symbolizes the soil of the country and the dark past and suffering endured by the Estonian people; white refers to the striving towards enlightenment and virtue, and is the color of birch bark and snow, as well as summer nights illuminated by the midnight sun.
