It is very nice & it is a must but it need more than 5 hours if you want to go in details, I faced problem with my trip advisor tickets, when I arrived they tried to scan the barcode it was wrong & even I have the printed paper & the application, but the stuff were very helpful the let me in in to all the facilities, (cause you need to scan the Barcode in three different places ) I was embarrassed but they said things happened & we believe you & the give me the access appreciate that from them.

The Musee de l'Armes des Invalides (or French Military Museum for the uninitiated!) is one of the must-see attractions in Paris, even if you're not a military buff. The complex is large and takes at least a half day to do it justice. The multiple galleries are comprehensive and cover centuries of French military campaigns. Impressive in its own right is the tomb of Emperor Napoleon which is located at the far end of the Museum complex. You can spend as little or as much time here as you like, but it takes a few hours just to do a quick walk through so be prepared for that. Highly recommended.

The museum is on the grounds of Les Invalides which is the National Residence of the Invalids. It is a huge group of buildings containing museums and monuments relating to the military history of France. One of the buildings is the “Musée de l'Armée”, which is the military museum of the Army of France. Besides the usual Military items you’d expect to see, with the admission ticket you also have access to Napoleon’s tomb and the Dome church containing the tomb. There is so much to see in Paris that I’m hesitant to say this is a must see, but it is really amazing. Highly recommend but it’ll take a good 3 hours to scratch the surface!
