Atomium, Brussels

Belgium (ⁱ/ˈbɛldʒəm/ bel-jəm), officially the Kingdom of Belgium, is a federal state in Western Europe. It is a founding member of the European Union and hosts the EU's headquarters, and those of several other major international organisations such as NATO. Belgium covers an area of 30,528 square kilometres (11,787 sq mi), and it has a population of about 11 million people. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups, the Dutch-speakers, mostly Flemish (about 60%), and the French-speakers, mostly Walloons (about 40%), plus a small group of German-speakers. Belgium's two largest regions are the Dutch-speaking region of Flanders in the north and the French-speaking southern region of Wallonia. The Brussels-Capital Region, officially bilingual, is a mostly French-speaking enclave within the Flemish Region. A German-speaking Community exists in eastern Wallonia. Belgium's linguistic diversity and related political conflicts are reflected in the political history and a complex system of government.

The Atomium is a monument in Brussels, originally built for Expo '58, the 1958 Brussels World's Fair. Designed by André Waterkeyn, it stands 102 metres (335 ft) tall. It has nine steel spheres connected so that the whole forms the shape of a unit cell of an iron crystal magnified 165 billion times.

Tubes connect the spheres along the 12 edges of the cube and all eight vertices to the centre. They enclose escalators connecting the spheres containing exhibit halls and other public spaces. The top sphere provides a panoramic view of Brussels. Each sphere is 18 metres in diameter. Three spheres are currently (2008) closed to visitors, others can be reached easily by escalators. The vertical vertex contains a lift which was very fast and advanced at the time of building (the speed is 5 m/s).

Brussels (French: Bruxelles, pronounced [bʁysɛl] ( listen); Dutch: Brussel, pronounced [ˈbrʏsəl] ( listen); German: Brüssel, pronounced [ˈbʁʏsəl]), officially the Brussels Region or Brussels-Capital Region (French:  Région de Bruxelles-Capitale (help·info), Dutch:  Brussels Hoofdstedelijk Gewest (help·info)), is the capital of Belgium and the de facto capital of the European Union (EU). It is also the largest urban area in Belgium, comprising 19 municipalities, including the municipality of the City of Brussels, which is the de jure capital of Belgium, in addition to the seat of the French Community of Belgium and of the Flemish Community.
