Mathildenhöhe Darmstadt | Germany

The Darmstadt Artists’ Colony on Mathildenhöhe, the highest elevation above the city of Darmstadt in west-central Germany, was established in 1897 by Ernst Ludwig, Grand Duke of Hesse, as a centre for emerging reform movements in architecture, arts and crafts. The buildings of the colony were created by its artist members as experimental early modernist living and working environments. The colony was expanded during successive international exhibitions in 1901, 1904, 1908 and 1914. Today, it offers a testimony to early modern architecture, urban planning and landscape design, all of which were influenced by the Arts and Crafts movement and the Vienna Secession. The serial property consists of two component parts including 23 elements, such as the Wedding Tower (1908), the Exhibition Hall (1908), the Plane Tree Grove (1833, 1904-14), the Russian Chapel of St. Maria Magdalena (1897-99), the Lily Basin, the Gottfried Schwab Memorial (1905), the Pergola and Garden (1914), the “Swan Temple” Garden Pavilion (1914), the Ernst Ludwig Fountain, and the 13 houses and artists’ studios that were built for the Darmstadt Artists’ Colony and for the international exhibitions. A Three House Group, built for the 1904 exhibition is an additional component.

Peking Man Site at Zhoukoudian | China

Scientific work at the site, which lies 42 km south-west of Beijing, is still underway. So far, it has led to the discovery of the remains of Sinanthropus pekinensis, who lived in the Middle Pleistocene, along with various objects, and remains of Homo sapiens sapiens dating as far back as 18,000–11,000 B.C. The site is not only an exceptional reminder of the prehistorical human societies of the Asian continent, but also illustrates the process of evolution.

Okavango Delta | Botswana

This delta in north-west Botswana comprises permanent marshlands and seasonally flooded plains. It is one of the very few major interior delta systems that do not flow into a sea or ocean, with a wetland system that is almost intact. One of the unique characteristics of the site is that the annual flooding from the River Okavango occurs during the dry season, with the result that the native plants and animals have synchronized their biological cycles with these seasonal rains and floods. It is an exceptional example of the interaction between climatic, hydrological and biological processes. The Okavango Delta is home to some of the world’s most endangered species of large mammal, such as the cheetah, white rhinoceros, black rhinoceros, African wild dog and lion.

Struve Geodetic Arc | Lithuania

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.

Sites of Japan’s Meiji Industrial Revolution: Iron and Steel, Shipbuilding and Coal Mining | Japan

The site encompasses a series of twenty three component parts, mainly located in the southwest of Japan. It bears testimony to the rapid industrialization of the country from the middle of the 19th century to the early 20th century, through the development of the iron and steel industry, shipbuilding and coal mining. The site illustrates the process by which feudal Japan sought technology transfer from Europe and America from the middle of the 19th century and how this technology was adapted to the country’s needs and social traditions. The site testifies to what is considered to be the first successful transfer of Western industrialization to a non-Western nation.
