Detail of the Maquette of Maastricht with a view of the fortifications to the west of the city. The scale model was made in 1974-1982, a genuine copy of the mid-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.
