L'arc de triomphe de l'Étoile, often called just l'Arc de Triomphe stands at the top of the avenue des Champs-Élysees on the place de l'Étoile. The arch is 50 meters (164 ft.) tall. It was ordered built by Napoleon Bonaparte and its construction took 80 years (1806-1836). Napoleon had been defeated at Waterloo in 1815 and ended up in exile. The Cadogan guidebook for Paris says that the arch "is not a tribute to Napoleon, although it certainly would have been had the emperor been around to finish it. The arch commemorates the armies of the Revolution..."
P.S. I'm still having a lot of trouble with our internet connection. My posting may be erratic for a few days. Besides, we have house guests arriving tomorrow, and we are really busy making the house ready after two years of confinement. And then yesterday there were reports that Covid19 is surging again in parts of France, most notably in Toulouse and the southwest. Wish us luck.
