Dutch Water Defence Lines

Extending 135 km around the city of Amsterdam, this defence line (built between 1883 and 1920) is the only example of a fortification based on the principle of controlling the waters. Since the 16th century, the people of the Netherlands have used their expert knowledge of hydraulic engineering for defence purposes. The centre of the country was protected by a network of 45 armed forts, acting in concert with temporary flooding from polders and an intricate system of canals and locks.

Oporto

The city of Oporto, built along the hillsides overlooking the mouth of the Douro river, is an outstanding urban landscape with a 2,000-year history. Its continuous growth, linked to the sea (the Romans gave it the name Portus, or port), can be seen in the many and varied monuments, from the cathedral with its Romanesque choir, to the neoclassical Stock Exchange and the typically Portuguese Manueline-style Church of Santa Clara.

Lake Baikal

Situated in south-east Siberia, the 3.15-million-ha Lake Baikal is the oldest (25 million years) and deepest (1,700 m) lake in the world. It contains 20% of the world's total unfrozen freshwater reserve. Known as the 'Galapagos of Russia', its age and isolation have produced one of the world's richest and most unusual freshwater faunas, which is of exceptional value to evolutionary science.

Volcanoes of Kamchatka

This is one of the most outstanding volcanic regions in the world, with a high density of active volcanoes, a variety of types, and a wide range of related features. The six sites included in the serial designation group together the majority of volcanic features of the Kamchatka peninsula. The interplay of active volcanoes and glaciers forms a dynamic landscape of great beauty. The sites contain great species diversity, including the world's largest known variety of salmonoid fish and exceptional concentra... Read More

Cuenca

Built by the Moors in a defensive position at the heart of the Caliphate of Cordoba, Cuenca is an unusually well-preserved medieval fortified city. Conquered by the Castilians in the 12th century, it became a royal town and bishopric endowed with important buildings, such as Spain's first Gothic cathedral, and the famous casas colgadas (hanging houses), suspended from sheer cliffs overlooking the Huécar river. Taking full advantage of its location, the city towers above the magnificent countryside.

La Lonja de la Seda de Valencia

Built between 1482 and 1533, this group of buildings was originally used for trading in silk (hence its name, the Silk Exchange) and it has always been a centre for commerce. It is a masterpiece of late Gothic architecture. The grandiose Sala de Contratación (Contract or Trading Hall), in particular, illustrates the power and wealth of a major Mediterranean mercantile city in the 15th and 16th centuries.

Gammelstad

Gammelstad, at the head of the Gulf of Bothnia, is the best-preserved example of a 'church village', a unique kind of village formerly found throughout northern Scandinavia. The 424 wooden houses, huddled round the early 15th-century stone church, were used only on Sundays and at religious festivals to house worshippers from the surrounding countryside who could not return home the same day because of the distance and difficult travelling conditions.

Laponian Area

The Arctic Circle region of northern Sweden is the home of the Saami people. It is the largest area in the world (and one of the last) with an ancestral way of life based on the seasonal movement of livestock. Every summer, the Saami lead their huge herds of reindeer towards the mountains through a natural landscape hitherto preserved, but now threatened by the advent of motor vehicles. Historical and ongoing geological processes can be seen in the glacial moraines and changing water courses.

Waterton Glacier

In 1932 Waterton Lakes National Park (Alberta, Canada) was combined with the Glacier National Park (Montana, United States) to form the world's first International Peace Park. Situated on the border between the two countries and offering outstanding scenery, the park is exceptionally rich in plant and mammal species as well as prairie, forest, and alpine and glacial features.

Aggtelek and Slovak Karst

The variety of formations and the fact that they are concentrated in a restricted area means that the 712 caves currently identified make up a typical temperate-zone karstic system. Because they display an extremely rare combination of tropical and glacial climatic effects, they make it possible to study geological history over tens of millions of years.

Lunenburg

Lunenburg is the best surviving example of a planned British colonial settlement in North America. Established in 1753, it has retained its original layout and overall appearance, based on a rectangular grid pattern drawn up in the home country. The inhabitants have managed to safeguard the city's identity throughout the centuries by preserving the wooden architecture of the houses, some of which date from the 18th century.

Rapa Nui

Rapa Nui, the indigenous name of Easter Island, bears witness to a unique cultural phenomenon. A society of Polynesian origin that settled there c. A.D. 300 established a powerful, imaginative and original tradition of monumental sculpture and architecture, free from any external influence. From the 10th to the 16th century this society built shrines and erected enormous stone figures known as moai , which created an unrivalled cultural landscape that continues to fascinate people throughout the world.

Santa Cruz de Mompox

Founded in 1540 on the banks of the River Magdalena, Mompox played a key role in the Spanish colonization of northern South America. From the 16th to the 19th century the city developed parallel to the river, with the main street acting as a dyke. The historic centre has preserved the harmony and unity of the urban landscape. Most of the buildings are still used for their original purposes, providing an exceptional picture of what a Spanish colonial city was like.

Tierradentro

Several monumental statues of human figures can be seen in the park, which also contains many hypogea dating from the 6th to the 10th century. These huge underground tombs (some burial chambers are up to 12 m wide) are decorated with motifs that reproduce the internal decor of homes of the period. They reveal the social complexity and cultural wealth of a pre-Hispanic society in the northern Andes.

San Agustín

The largest group of religious monuments and megalithic sculptures in South America stands in a wild, spectacular landscape. Gods and mythical animals are skilfully represented in styles ranging from abstract to realist. These works of art display the creativity and imagination of a northern Andean culture that flourished from the 1st to the 8th century.

Kutna Hora

Kutná Hora developed as a result of the exploitation of the silver mines. In the 14th century it became a royal city endowed with monuments that symbolized its prosperity. The Church of St Barbara, a jewel of the late Gothic period, and the Cathedral of Our Lady at Sedlec, which was restored in line with the Baroque taste of the early 18th century, were to influence the architecture of central Europe. These masterpieces today form part of a well-preserved medieval urban fabric with some particularly fine pr... Read More

Roskilde Cathedral

Built in the 12th and 13th centuries, this was Scandinavia's first Gothic cathedral to be built of brick and it encouraged the spread of this style throughout northern Europe. It has been the mausoleum of the Danish royal family since the 15th century. Porches and side chapels were added up to the end of the 19th century. Thus it provides a clear overview of the development of European religious architecture.

Avignon

In the 14th century, this city in the South of France was the seat of the papacy. The Palais des Papes, an austere-looking fortress lavishly decorated by Simone Martini and Matteo Giovanetti, dominates the city, the surrounding ramparts and the remains of a 12th-century bridge over the Rhone. Beneath this outstanding example of Gothic architecture, the Petit Palais and the Romanesque Cathedral of Notre-Dame-des-Doms complete an exceptional group of monuments that testify to the leading role played by Avigno...

Messel Pit

Messel Pit is the richest site in the world for understanding the living environment of the Eocene, between 57 million and 36 million years ago. In particular, it provides unique information about the early stages of the evolution of mammals and includes exceptionally well-preserved mammal fossils, ranging from fully articulated skeletons to the contents of stomachs of animals of this period.

Siena

Siena is the embodiment of a medieval city. Its inhabitants pursued their rivalry with Florence right into the area of urban planning. Throughout the centuries, they preserved their city's Gothic appearance, acquired between the 12th and 15th centuries. During this period the work of Duccio, the Lorenzetti brothers and Simone Martini was to influence the course of Italian and, more broadly, European art. The whole city of Siena, built around the Piazza del Campo, was devised as a work of art that blends int... Read More

Crespi d'Adda

Crespi d'Adda in Capriate San Gervasio in Lombardy is an outstanding example of the 19th- and early 20th-century 'company towns' built in Europe and North America by enlightened industrialists to meet the workers' needs. The site is still remarkably intact and is partly used for industrial purposes, although changing economic and social conditions now threaten its survival.

Ferrara

Ferrara, which grew up around a ford over the River Po, became an intellectual and artistic centre that attracted the greatest minds of the Italian Renaissance in the 15th and 16th centuries. Here, Piero della Francesca, Jacopo Bellini and Andrea Mantegna decorated the palaces of the House of Este. The humanist concept of the 'ideal city' came to life here in the neighbourhoods built from 1492 onwards by Biagio Rossetti according to the new principles of perspective. The completion of this project marked th... Read More

Naples

From the Neapolis founded by Greek settlers in 470 B.C. to the city of today, Naples has retained the imprint of the successive cultures that emerged in Europe and the Mediterranean basin. This makes it a unique site, with a wealth of outstanding monuments such as the Church of Santa Chiara and the Castel Nuovo.

Shirakawa go and Gokayama

Located in a mountainous region that was cut off from the rest of the world for a long period of time, these villages with their Gassho-style houses subsisted on the cultivation of mulberry trees and the rearing of silkworms. The large houses with their steeply pitched thatched roofs are the only examples of their kind in Japan. Despite economic upheavals, the villages of Ogimachi, Ainokura and Suganuma are outstanding examples of a traditional way of life perfectly adapted to the environment and people's s... Read More

Luang Prabang

Luang Prabang is an outstanding example of the fusion of traditional architecture and Lao urban structures with those built by the European colonial authorities in the 19th and 20th centuries. Its unique, remarkably well-preserved townscape illustrates a key stage in the blending of these two distinct cultural traditions.
