Brabant, the central and metropolitan province of Belgium, is formed out of part of the ancient duchy. From 1815 to 1830, that is to say, during the existence of the kingdom of the Netherlands, Belgian Brabant was distinguished from Dutch by the employment of the geographical terms South and North. The surface of Brabant is undulating, and the highest points, some 400 ft. in altitude, are to be found at and near Mont St Jean. The province is well cultivated, and the people are well known for their industry. There are valuable stone quarries, and many manufactures flourish in the smaller towns, such as Ottignies, as well as in the larger cities of Brussels and Louvain. Brabant contains 820,740 acres or 1268 sq. m. Its principal towns are Brussels, Louvain, Nivelles, Hal, Ottignies, and its three administrative divisions are named after the first three of those towns. They are subdivided into 50 cantons and 344 communes. In 1904 the population of the province was 1,366,389 or a proportion of 1077 per sq. m.
