Invalides is a military museum chronicling WWI, WWII and the medieval wars especially that of Napoleon Bonaparte’s conquests. I like best the Medieval Room, which exhibits armors and a remarkable collection of swords. Napoleon has a tomb inside in what is called the Dome Church, a military pantheon. Surrounded by other great leaders, the emperor is encased in 5 successive coffins, one made of tin, one of mahogany, two of lead and one of ebony. In 1989, the massive dome and its decorations directly above Napoleon’s sarcophagus were re-gilded using 12 kilograms of real gold!
