The Athena project was made to renovate the museum of the Army, housed in the Hotel of the Invalides. Started in 2000, this project finished lately a significant step with the recent reopening of the new rooms of armors and old weapons from XIIIth to the XVIIth century installed along the main courtyard.  These rooms are usually the most appreciated by the visitors. These collections of armors compete with the most beautiful of Europe, Vienna and Madrid.  It is the third collection in the world for its variety and its richness : 2500 m2 of steel clothing tell us the art of the war. Armors of tournaments, parts of hunting, combat, in Occident and the East, recall us the untiring desire of conquest of the men. In icon headlight of this visit, let us rediscover the frescos murals of Parrocel, completely renovated in the historical refectory as well as the arsenal, aligning an army of armors ready for all the attacks.
