Detail of the Maquette of Maastricht showing the former inundation area De Kommen south of the city. The scale model was made in 1974-82, a genuine copy of the 18th-century original made for King Louis XV of France (now in the Palais des Beaux-Arts in Lille). Usually only the central part is on display in Centre Céramique; once in five years the whole maquette is exhibited, as is the case here.
