Belgium has three main geographical regions: the coastal plain in the north-west, the central plateau, and the Ardennes uplands in the south-east.
Much of Belgium is relatively flat but the Ardennes in the southeast are forested and hilly with steep river valleys. The rivers which flow through Belgium include the Scheldt, the Sambre and the Meuse.
Brussels is the capital city; Antwerp, is Belgium's leading port and a major European port. The oldest cities in Belgium are Ghent and Brugge.
