Struve Geodetic Arc (Aavasaksa) | Finland

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.

Belfries of Belgium and France (St. Rumbolds Tower of the Cathedral, Mechelen) | Belgium

Twenty-three belfries in the north of France and the belfry of Gembloux in Belgium were inscribed in 2005, as an extension to the 32 Belgian belfries inscribed in 1999 as Belfries of Flanders and Wallonia. Built between the 11th and 17th centuries, they showcase the Roman, Gothic, Renaissance and Baroque styles of architecture. They are highly significant tokens of the winning of civil liberties. While Italian, German and English towns mainly opted to build town halls, in part of north-western Europe, greater emphasis was placed on building belfries. Compared with the keep (symbol of the seigneurs) and the bell-tower (symbol of the Church), the belfry, the third tower in the urban landscape, symbolizes the power of the aldermen. Over the centuries, they came to represent the influence and wealth of the towns.

Maulbronn Monastery Complex | Germany

Founded in 1147, the Cistercian Maulbronn Monastery is considered the most complete and best-preserved medieval monastic complex north of the Alps. Surrounded by fortified walls, the main buildings were constructed between the 12th and 16th centuries. The monastery's church, mainly in Transitional Gothic style, had a major influence in the spread of Gothic architecture over much of northern and central Europe. The water-management system at Maulbronn, with its elaborate network of drains, irrigation canals and reservoirs, is of exceptional interest.
