The
Flemish Diamond (in
Dutch:
Vlaamse Ruit) is the
Flemish reference to a network of four
metropolitan areas in
Belgium, three of which are in the central provinces of
Flanders, together with the
Brussels Capital Region. It consists of four agglomerations which form the four corners of a diamond shape:
Brussels,
Ghent,
Antwerp and
Leuven. Over five million people live in this area, with a population density of more than 800 per square kilometre.<ref
