The Wadden Sea is the largest unbroken system of intertidal sand and mud flats in the world.
The site covers the Dutch Wadden Sea Conservation Area, the German Wadden Sea National Parks of Lower Saxony and Schleswig-Holstein, and most of the Danish Wadden Sea maritime conservation area.
It is a large, temperate, relatively flat coastal wetland environment, formed by the intricate interactions between physical and biological factors that have given rise to a multitude of transitional habitats with tidal channels, sandy shoals, sea-grass meadows, mussel beds, sandbars, mudflats, salt marshes, estuaries, beaches and dunes.
The area is home to numerous plant and animal species, including marine mammals such as the harbour seal, grey seal and harbour porpoise.
Wadden Sea is one of the last remaining large-scale, intertidal ecosystems where natural processes continue to function largely undisturbed.

The churches and convents of Goa, the former capital of the Portuguese Indies – particularly the Church of Bom Jesus, which contains the tomb of St Francis-Xavier – illustrate the evangelization of Asia.
These monuments were influential in spreading forms of Manueline, Mannerist and Baroque art in all the countries of Asia where missions were established.

Lübeck – the former capital and Queen City of the Hanseatic League – was founded in the 12th century and prospered until the 16th century as the major trading centre for northern Europe.
It has remained a centre for maritime commerce to this day, particularly with the Nordic countries.
Despite the damage it suffered during the Second World War, the basic structure of the old city, consisting mainly of 15th- and 16th-century patrician residences, public monuments (the famous Holstentor brick gate), churches and salt storehouses, remains unaltered.

The Royal Saltworks of Arc-et-Senans, near Besançon, was built by Claude Nicolas Ledoux.
Its construction, begun in 1775 during the reign of Louis XVI, was the first major achievement of industrial architecture, reflecting the ideal of progress of the Enlightenment.
The vast, semicircular complex was designed to permit a rational and hierarchical organization of work and was to have been followed by the building of an ideal city, a project that was never realized.
The Great Saltworks of Salins-les-Bains was active for at least 1200 years until stopping activity in 1962.
From 1780 to 1895, its salt water travelled through 21 km of wood pipes to the Royal Saltworks of Arc-et-Senans.
It was built near the immense Chaux Forest to ensure its supply of wood for fuel.
The Saltworks of Salins shelters an underground gallery from the 13th century including a hydraulic pump from the 19th century that still functions.
The boiler house demonstrates the difficulty of the saltworkers’ labour to collect the “White Gold”.

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.
