The castles of Beaumaris and Harlech (largely the work of the greatest military engineer of the time, James of St George) and the fortified complexes of Caernarfon and Conwy are located in the former principality of Gwynedd, in north Wales. These extremely well-preserved monuments are examples of the colonization and defence works carried out throughout the reign of Edward I (1272–1307) and the military architecture of the time.

Ironbridge is known throughout the world as the symbol of the Industrial Revolution. It contains all the elements of progress that contributed to the rapid development of this industrial region in the 18th century, from the mines themselves to the railway lines. Nearby, the blast furnace of Coalbrookdale, built in 1708, is a reminder of the discovery of coke. The bridge at Ironbridge, the world's first bridge constructed of iron, had a considerable influence on developments in the fields of technology and architecture.

In the 18th century a designed landscape of exceptional beauty was created around the ruins of the Cistercian Fountains Abbey, in Yorkshire. The spectacular ruins of the 12th century abbey and water mill, the Jacobean mansion of Fountains Hall, the Victorian masterpiece St Mary’s Church and one of the most magnificent Georgian water gardens ever created, make this a landscape of outstanding merit.

Stonehenge and Avebury, in Wiltshire, are among the most famous groups of megaliths in the world. The two sanctuaries consist of circles of menhirs arranged in a pattern whose astronomical significance is still being explored. These holy places and the nearby Neolithic sites are an incomparable testimony to prehistoric times.

This volcanic archipelago, with its spectacular landscapes, is situated off the coast of the Hebrides and comprises the islands of Hirta, Dun, Soay and Boreray. It has some of the highest cliffs in Europe, which have large colonies of rare and endangered species of birds, especially puffins and gannets. The archipelago, uninhabited since 1930, bears the evidence of more than 2,000 years of human occupation in the extreme conditions prevalent in the Hebrides. Human vestiges include built structures and field systems, the cleits and the traditional Highland stone houses. They feature the vulnerable remains of a subsistence economy based on the products of birds, agriculture and sheep farming.

Durham Cathedral was built in the late 11th and early 12th centuries to house the relics of St Cuthbert (evangelizer of Northumbria) and the Venerable Bede. It attests to the importance of the early Benedictine monastic community and is the largest and finest example of Norman architecture in England. The innovative audacity of its vaulting foreshadowed Gothic architecture. Behind the cathedral stands the castle, an ancient Norman fortress which was the residence of the prince-bishops of Durham.

The Giant's Causeway lies at the foot of the basalt cliffs along the sea coast on the edge of the Antrim plateau in Northern Ireland. It is made up of some 40,000 massive black basalt columns sticking out of the sea. The dramatic sight has inspired legends of giants striding over the sea to Scotland. Geological studies of these formations over the last 300 years have greatly contributed to the development of the earth sciences, and show that this striking landscape was caused by volcanic activity during the Tertiary, some 50–60 million years ago.

Blenheim Palace, near Oxford, stands in a romantic park created by the famous landscape gardener 'Capability' Brown. It was presented by the English nation to John Churchill, first Duke of Marlborough, in recognition of his victory in 1704 over French and Bavarian troops. Built between 1705 and 1722 and characterized by an eclectic style and a return to national roots, it is a perfect example of an 18th-century princely dwelling.

The ‘Roman Limes’ represents the border line of the Roman Empire at its greatest extent in the 2nd century AD. It stretched over 5,000 km from the Atlantic coast of northern Britain, through Europe to the Black Sea, and from there to the Red Sea and across North Africa to the Atlantic coast. The remains of the Limes today consist of vestiges of built walls, ditches, forts, fortresses, watchtowers and civilian settlements. Certain elements of the line have been excavated, some reconstructed and a few destroyed. The two sections of the Limes in Germany cover a length of 550 km from the north-west of the country to the Danube in the south-east. The 118-km-long Hadrian’s Wall (UK) was built on the orders of the Emperor Hadrian c. AD 122 at the northernmost limits of the Roman province of Britannia. It is a striking example of the organization of a military zone and illustrates the defensive techniques and geopolitical strategies of ancient Rome. The Antonine Wall, a 60-km long fortification in Scotland was started by Emperor Antonius Pius in 142 AD as a defense against the “barbarians” of the north. It constitutes the northwestern-most portion of the Roman Limes.

Founded by the Romans as a thermal spa, Bath became an important centre of the wool industry in the Middle Ages. In the 18th century, under George III, it developed into an elegant town with neoclassical Palladian buildings, which blend harmoniously with the Roman baths.

Westminster Palace, rebuilt from the year 1840 on the site of important medieval remains, is a fine example of neo-Gothic architecture. The site – which also comprises the small medieval Church of Saint Margaret, built in Perpendicular Gothic style, and Westminster Abbey, where all the sovereigns since the 11th century have been crowned – is of great historic and symbolic significance.

Canterbury, in Kent, has been the seat of the spiritual head of the Church of England for nearly five centuries. Canterbury's other important monuments are the modest Church of St Martin, the oldest church in England; the ruins of the Abbey of St Augustine, a reminder of the saint's evangelizing role in the Heptarchy from 597; and Christ Church Cathedral, a breathtaking mixture of Romanesque and Perpendicular Gothic, where Archbishop Thomas Becket was murdered in 1170.

The massive White Tower is a typical example of Norman military architecture, whose influence was felt throughout the kingdom. It was built on the Thames by William the Conqueror to protect London and assert his power. The Tower of London – an imposing fortress with many layers of history, which has become one of the symbols of royalty – was built around the White Tower.

Edinburgh has been the Scottish capital since the 15th century. It has two distinct areas: the Old Town, dominated by a medieval fortress; and the neoclassical New Town, whose development from the 18th century onwards had a far-reaching influence on European urban planning. The harmonious juxtaposition of these two contrasting historic areas, each with many important buildings, is what gives the city its unique character.

The ensemble of buildings at Greenwich, an outlying district of London, and the park in which they are set, symbolize English artistic and scientific endeavour in the 17th and 18th centuries. The Queen's House (by Inigo Jones) was the first Palladian building in England, while the complex that was until recently the Royal Naval College was designed by Christopher Wren. The park, laid out on the basis of an original design by André Le Nôtre, contains the Old Royal Observatory, the work of Wren and the scientist Robert Hooke.

The group of Neolithic monuments on Orkney consists of a large chambered tomb (Maes Howe), two ceremonial stone circles (the Stones of Stenness and the Ring of Brodgar) and a settlement (Skara Brae), together with a number of unexcavated burial, ceremonial and settlement sites. The group constitutes a major prehistoric cultural landscape which gives a graphic depiction of life in this remote archipelago in the far north of Scotland some 5,000 years ago.

The area around Blaenavon is evidence of the pre-eminence of South Wales as the world's major producer of iron and coal in the 19th century. All the necessary elements can still be seen - coal and ore mines, quarries, a primitive railway system, furnaces, workers' homes, and the social infrastructure of their community.

The cliff exposures along the Dorset and East Devon coast provide an almost continuous sequence of rock formations spanning the Mesozoic Era, or some 185 million years of the earth's history. The area's important fossil sites and classic coastal geomorphologic features have contributed to the study of earth sciences for over 300 years.

The Derwent Valley in central England contains a series of 18th- and 19th- century cotton mills and an industrial landscape of high historical and technological interest. The modern factory owes its origins to the mills at Cromford, where Richard Arkwright's inventions were first put into industrial-scale production. The workers' housing associated with this and the other mills remains intact and illustrate the socio-economic development of the area.

New Lanark is a small 18th- century village set in a sublime Scottish landscape where the philanthropist and Utopian idealist Robert Owen moulded a model industrial community in the early 19th century. The imposing cotton mill buildings, the spacious and well-designed workers' housing, and the dignified educational institute and school still testify to Owen's humanism.

Saltaire, West Yorkshire, is a complete and well-preserved industrial village of the second half of the 19th century. Its textile mills, public buildings and workers' housing are built in a harmonious style of high architectural standards and the urban plan survives intact, giving a vivid impression of Victorian philanthropic paternalism.

This historic landscape garden features elements that illustrate significant periods of the art of gardens from the 18th to the 20th centuries. The gardens house botanic collections (conserved plants, living plants and documents) that have been considerably enriched through the centuries. Since their creation in 1759, the gardens have made a significant and uninterrupted contribution to the study of plant diversity and economic botany.

Much of the landscape of Cornwall and West Devon was transformed in the 18th and early 19th centuries as a result of the rapid growth of pioneering copper and tin mining. Its deep underground mines, engine houses, foundries, new towns, smallholdings, ports and harbours, and their ancillary industries together reflect prolific innovation which, in the early 19th century, enabled the region to produce two-thirds of the world’s supply of copper. The substantial remains are a testimony to the contribution Cornwall and West Devon made to the Industrial Revolution in the rest of Britain and to the fundamental influence the area had on the mining world at large. Cornish technology embodied in engines, engine houses and mining equipment was exported around the world. Cornwall and West Devon were the heartland from which mining technology rapidly spread.

Situated in north-eastern Wales, the 18 kilometre long Pontcysyllte Aqueduct and Canal is a feat of civil engineering of the Industrial Revolution, completed in the early years of the 19th century. Covering a difficult geographical setting, the building of the canal required substantial, bold civil engineering solutions, especially as it was built without using locks. The aqueduct is a pioneering masterpiece of engineering and monumental metal architecture, conceived by the celebrated civil engineer Thomas Telford. The use of both cast and wrought iron in the aqueduct enabled the construction of arches that were light and d strong, producing an overall effect that is both monumental and elegant. The property is inscribed as a masterpiece of creative genius, and as a remarkable synthesis of expertise already acquired in Europe. It is also recognized as an innovative ensemble that inspired many projects all over the world.

This transnational serial property comprises four congregational settlements in four countries representing the transnational scope and consistency of the international Moravian community as a global network of the Moravian Church: Christiansfeld (Denmark), Herrnhut (Germany), Gracehill (United Kingdom of Great Britain and Northern Ireland) and Bethlehem (United States of America). These settlements were established according to overarching planning principles that reflected the ideals of the Moravian Church, as expressed in their plans and democratic organisation. Each architectural ensemble bears witness to the Moravian Church’s vision of a unified, coherent urban design, inspired by the concept of an “ideal city” developed by the Church during its formative phase in the 18th and beginning of the 19th enturies. Distinctive Moravian buildings include a particular type of Gemeinhaus (congregation building), church, choir houses, as well as a nearby God’s Acre (cemetery). Each settlement has its own architectural character based on an original Moravian Church Civic Baroque style but adapted to local conditions. Present today in each component part is an active congregation whose continuation of traditions forms a living Moravian heritage.

This railway bridge, crossing the Forth estuary in Scotland, had the world’s longest spans (541 m) when it opened in 1890. It remains one of the greatest cantilever trussed bridges and continues to carry passengers and freight. Its distinctive industrial aesthetic is the result of a forthright and unadorned display of its structural components. Innovative in style, materials and scale, the Forth Bridge marks an important milestone in bridge design and construction during the period when railways came to dominate long-distance land travel.

Located in northwest England, the English Lake District is a mountainous area, whose valleys have been modelled by glaciers in the Ice Age and subsequently shaped by an agro-pastoral land-use system characterized by fields enclosed by walls. The combined work of nature and human activity has produced a harmonious landscape in which the mountains are mirrored in the lakes. Grand houses, gardens and parks have been purposely created to enhance the landscape’s beauty. This landscape was greatly appreciated from the 18th century onwards by the Picturesque and later Romantic movements, which celebrated it in paintings, drawings and words. It also inspired an awareness of the importance of beautiful landscapes and triggered early efforts to preserve them.

Located in a rural area of northwest England, free from radio interference, Jodrell Bank is one of the world's leading radio astronomy observatories. At the beginning of its use, in 1945, the property housed research on cosmic rays detected by radar echoes. This observatory, which is still in operation, includes several radio telescopes and working buildings, including engineering sheds and the Control Building. Jodrell Bank has had substantial scientific impact in fields such as the study of meteors and the moon, the discovery of quasars, quantum optics, and the tracking of spacecraft. This exceptional technological ensemble illustrates the transition from traditional optical astronomy to radio astronomy (1940s to 1960s), which led to radical changes in the understanding of the universe.

This transnational serial property comprises eleven spa towns, located in seven European countries: Baden bei Wien (Austria); Spa (Belgium); Františkovy Lázně; Karlovy Vary; Mariánské Lázně (Czechia); Vichy (France); Bad Ems; Baden-Baden; Bad Kissingen (Germany); Montecatini Terme (Italy); and City of Bath (United Kingdom). All of these towns developed around natural mineral water springs. They bear witness to the international European spa culture that developed from the early 18th century to the 1930s, leading to the emergence of grand international resorts that impacted urban typology around ensembles of spa buildings such as baths, kurhaus and kursaal (buildings and rooms dedicated to therapy), pump rooms, drinking halls, colonnades and galleries designed to harness the natural mineral water resources and to allow their practical use for bathing and drinking. Related facilities include gardens, assembly rooms, casinos, theatres, hotels and villas, as well as spa-specific support infrastructure. These ensembles are all integrated into an overall urban context that includes a carefully managed recreational and therapeutic environment in a picturesque landscape. Together, these sites embody the significant interchange of human values and developments in medicine, science and balneology.

The Slate Landscape of Northwest Wales illustrates the transformation that industrial slate quarrying and mining brought about in the traditional rural environment of the mountains and valleys of the Snowdon massif. The territory, extending from mountain-top to sea-coast, presented opportunities and constraints that were used and challenged by the large-scale industrial processes undertaken by landowners and capital investors, which reshaped the agricultural landscape into an industrial centre for slate production during the Industrial Revolution (1780-1914). The serial property comprises six components each encompassing relict quarries and mines, archaeological sites related to slate industrial processing, historical settlements, both living and relict, historic gardens and grand country houses, ports, harbours and quays, and railway and road systems illustrating the functional and social linkages of the relict slate industrial landscape. The property was internationally significant not only for the export of slates, but also for the export of technology and skilled workers from the 1780s to the early 20th century. It played a leading role in the field and constituted a model for other slate quarries in different parts of the world. It offers an important and remarkable example of interchange of materials, technology and human values.

The serial property, located in the Highland Region of Scotland, is considered the most outstanding example of an actively accumulating blanket bog landscape. This peatland ecosystem, which has been accumulating for the past 9,000 years, provides a diversity of habitats home to a distinct combination of bird species and displays a remarkable diversity of features not found anywhere else on Earth. Peatlands play an important role in storing carbon and the property’s ongoing peat-forming ecological processes continue to sequester carbon on a very large scale, representing a significant research and educational resource.
