The Arc de Triomphe, Paris at 162′ feet and 150′ wide is much larger than I expected. Constructed between 1806 and 1836 it is situated on the western end of the Champs-Elysees. Beneath the Arc is the Tomb of the Unknown Soldier from World War I. Various victory parades have traveled through and later around the structure including the Germans in 1940 and the French and their allies in 1944/45. More information can be found here.
As much I was impressed with the Arc itself, I was equally impressed with the six lane traffic circle that surrounds it. There are no traffic lines and it was a thrill. Glad I wasn’t driving!
