I had no idea the Hôtel des Invalides even existed. Had it known I would have gone there. Regarding Napoleon I was under the impression he died in St Helena island and was buried there. Apparently his body was sent back to France.
Regarding your comments about the virus, how is the status of vaccinations in France. Here they're becoming more and more available as the days pass. I believe you can even make an appointment at one of the many vaccination centers in town. It's important to vaccinate as many people as possible. The different strains you refer to happen when Covid viruses make copies of themselves that aren't exactly the same.
Well, The dome des Invalides is actually not very far from the Mcdonald of the Champs Elysées, roughly 2 kms away on foot. During this visit there weren't many visitors, maybe many tourists don't know this museum. I was accompanied by my father, at this time he was pretty fine. He died a few months later of cancer. But visiting the Army museum is not very interesting unless one knows French history like you do anyway. The first tomb of Napoleon was in St Helena after he died in 1821 indeed. During the 1830s—an era we know from Les Miserables—France simmered and rioted. In 1840, to appease various political factions, King Louis-Philippe authorized the return to France of Napoleon Bonaparte’s body. The French call that day Le Retour des Cendres, which translates into “the Return of the Ashes.” But Napoleon Bonaparte wasn’t cremated. In fact, when he was exhumed on St Helena his body was exceptionally well-preserved.
In France only 10% of the population have been vaccinated due to the lack of doses of vaccine.
