Rupelmonde is a town in the municipality of Kruibeke, in the Belgian province of East Flanders. It stands on the bank of the river Schelde opposite the confluence of the eponymous Rupel, and is famed for its sundials as well as having what is probably Belgium's only tidemill. It is the birthplace of Gerardus Mercator, a famous Belgian cartographer, who was imprisoned for several years in the castle there, a remnant of which today serves as a museum.
