Edited sentence: Belgians made historical contributions to the development of science and technology.Each municipality belongs to only one of four linguistic regions: the Dutch-speaking, the French-speaking, the German-speaking region and the Dutch-French bilingual region of Brussels.However there are some exceptions: in some few municipalities bordering the linguistic regions — the so-called communes with special status or communes with linguistic facilities— other languages can be used to contact local authorities.In each of these linguistic regions the use of languages for contacts with public authorities, as regards administration, the law, education and labour relations in companies is ruled by the law: in the Dutch-speaking region, the official language is Dutch, in the French-speaking region, French, in the German-speaking region, German, and, in the Dutch-French bilingual region of Brussels, both French and Dutch on an equal footing.The Dutch-speaking region is the territory of the Flanders Region; the German-speaking region is the territory of the German-speaking Community; the bilingual region of Brussels is the territory of the Region Brussels-Capital; the French-speaking region corresponds to the rest of the Belgian territory (Wallonia without the territory of the German-speaking Community).The Port of Antwerp is the second-largest European port and Zeebrugge, the modern port of Bruges, is a very important European port as well.The most densely inhabited areas are the Flemish Diamond, outlined by the Antwerp-Leuven-Brussels-Ghent agglomerations, and other important urban centres as Liège, Charleroi, Bruges, Namur and Mons.Though there is no official census on the use of languages in Belgium, each municipality's official language is univoquely determined by the law
