Cordoba's period of greatest glory began in the 8th century after the Moorish conquest, when some 300 mosques and innumerable palaces and public buildings were built to rival the splendours of Constantinople, Damascus and Baghdad. In the 13th century, under Ferdinand III, the Saint, Cordoba's Great Mosque was turned into a cathedral and new defensive structures, particularly the Alcázar de los Reyes Cristianos and the Torre Fortaleza de la Calahorra, were erected.

The Virgin Komi Forests cover 3.28 million ha of tundra and mountain tundra in the Urals, as well as one of the most extensive areas of virgin boreal forest remaining in Europe. This vast area of conifers, aspens, birches, peat bogs, rivers and natural lakes has been monitored and studied for over 50 years. It provides valuable evidence of the natural processes affecting biodiversity in the taiga.
The 'Venice of the North', with its numerous canals and more than 400 bridges, is the result of a vast urban project begun in 1703 under Peter the Great. Later known as Leningrad (in the former USSR), the city is closely associated with the October Revolution. Its architectural heritage reconciles the very different Baroque and pure neoclassical styles, as can be seen in the Admiralty, the Winter Palace, the Marble Palace and the Hermitage.
These four churches, the first of which was built by the Spanish in the late 16th century, are located in Manila, Santa Maria, Paoay and Miag-ao. Their unique architectural style is a reinterpretation of European Baroque by Chinese and Philippine craftsmen.
Although severely damaged by earthquakes, this 'City of the Kings' was, until the middle of the 18th century, the capital and most important city of the Spanish dominions in South America. Many of its buildings, such as the Convent of San Francisco (the largest of its type in this part of the world), are the result of collaboration between local craftspeople and others from the Old World.
The Chimu Kingdom, with Chan Chan as its capital, reached its apogee in the 15th century, not long before falling to the Incas. The planning of this huge city, the largest in pre-Columbian America, reflects a strict political and social strategy, marked by the city's division into nine 'citadels' or 'palaces' forming autonomous units.

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.
This group of petroglyphs in the Alta Fjord, near the Arctic Circle, bears the traces of a settlement dating from c. 4200 to 500 B.C. The thousands of paintings and engravings add to our understanding of the environment and human activities on the fringes of the Far North in prehistoric times.
Since the pre-Roman period, a fortified settlement has existed on the hill where Carcassonne now stands. In its present form it is an outstanding example of a medieval fortified town, with its massive defences encircling the castle and the surrounding buildings, its streets and its fine Gothic cathedral. Carcassonne is also of exceptional importance because of the lengthy restoration campaign undertaken by Viollet-le-Duc, one of the founders of the modern science of conservation.
