The famous Arc de Triomphe is one of the most famous monuments in Paris said to house the tomb of unknown soldier. It stands in the centre of the Place Charles de Gaulle at 50 meters high and 45 meters wide (164 feet high and 147.6 feet wide).
The Arc is conspicuously located on the right bank of the Seine at the center of a dodecagonal configuration of twelve radiating avenues. It was commissioned in 1806 after the victory at Austerlitz by Emperor Napoleon at the peak of his fortunes. Laying the foundations alone took two years and, in 1810, when Napoleon entered Paris from the west with his bride Archduchess Marie-Louise of Austria, he had a wooden mock-up of the completed arch constructed.
I wish I had my little fitbit thingy when I was in Paris, because I walked and walked, have no idea how many miles I put around there in a few days. By the end of the day my feet were killing me and I had to change different shoes from preventing getting blisters, as the shoes I had were not the most comfortable walking shoes for 8-10 hours day, too late to discover.
