Detail of the Maquette of Maastricht with a view of the fortifications to the west of the city. The scale model was made in 1974-82 after the 18th-century original made for King Louis XV of France (now in the Palais des Beaux-Arts in Lille). The area depicted here is the "Hoge Fronten" fortifications between Brussels Gate ("1") and Lindenkruis Gate ("2").
