Belgium, a country in Western Europe, is known for medieval towns, Renaissance architecture and as headquarters of the European Union and NATO. The country has distinctive regions including Dutch-speaking Flanders to the north, French-speaking Wallonia to the south and a German-speaking community to the east. The bilingual capital, Brussels, has ornate guildhalls at Grand-Place and elegant art-nouveau buildings.

Belgium is a parliamentary constitutional monarchy with a complex federal system structured on regional and linguistic grounds. The country is divided into three highly autonomous regions: the Flemish Region (Flanders) in the north, the Walloon Region (Wallonia) in the south, and the Brussels-Capital Region in the middle. Brussels is the smallest region but also the most densely populated and the richest by GDP per capita.
