Musée des Plans-Reliefs

The Musée des Plans-Reliefs 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'. The models gave particular attention to the city fortifications and topographic features such as hills and harbors. In 1700, Louis XIV installed the collection in the Louvre.
