Musée National de la Légion d'Honneur
A must for military-history buffs, the National Museum of the Legion of Honor is dedicated to French and foreign military leaders. Housed in an elegant mansion just across from the Musée d'Orsay, it features a broad collection of military decorations dating from as early as the First Crusade in the 11th century, themed paintings, and video tributes to various luminaries—including U.S. general Dwight Eisenhower, a Légion member who led the Allied liberation of France in 1944. The palatial complex was completed in 1788 and acquired by the Legion of Honor in 1804.
