The gilded dome of L'Hotel National des Invalides, or the National Residence of the Invalids, a complex of buildings in the seventh arrondissement. It mostly pertains to the military history of France, as it housed a hospital and retirement home for veterans, which was its original purpose. There is also a military museum and a burial site of French war heroes, at least the ones who didn't make it into the Pantheon! It was built under Louis XIV, beginning in 1670, occupying a site formerly in the suburban plain of Grenelle. It is perhaps most famous for the July 14, 1789 incident when it was stormed by rioters who stole cannons and muskets stored there, used against the assault on the Bastille later in the day. It's also the site of Napoleon's tomb: he's interred under the dome. Its characteristic dome is perhaps one of the more recognizable architectural features in Paris.
