Musée des Plans-Reliefs
The Musée des Plans-Reliefs (French pronunciation: [myze de plɑ̃ ʁəljɛf]) is a museum of military models located within the Hôtel des Invalides in the 7th arrondissement of Paris, France. The construction of models dates to 1668, when François-Michel le Tellier, Marquis de Louvois and minister of war to Louis XIV, began a collection of three-dimensional models of fortified cities for military purposes, known as 'plans-relief'.
