ST NICOLAS, a town of Belgium in the province of East Flanders, about 12 m. S.W. of Antwerp. Pop. (1904), 32,767. It is the principal town of Waes, formerly a district of bleak and barren downs, but now the most productive part of Belgium. St Nicolas is the centre and distributing point of this district, being an important junction on the direct line from Antwerp to Ghent; it has also many manufactures of its own. The principal church dedicated to St Nicolas was finished in 1696, but the other public buildings are only of the 19th century.
