Place de la Concorde is the largest square in Paris and one of the loudest, an open octagon with traffic running round every side. In the middle stands an obelisk from the temple at Luxor, about 3,300 years old, raised here in October 1836 in front of a crowd of two hundred thousand. Two fountains and a ring of eight seated stone women, one for each of eight French cities, stand around it. Crossing to the middle takes patience.
The square was drawn as a setting for a statue of Louis XV on horseback. In 1792 a crowd pulled that statue down and the guillotine went up in its place. Over the next two and a half years more than a thousand people were beheaded where you are standing, among them Louis XVI, Marie-Antoinette, Danton and Robespierre. Carts took the bodies to a pit outside the square, and the government then renamed it Concorde, meaning agreement. No king, emperor or republic could later agree on whose statue belonged in the middle, which is how a stone from Egypt became the one thing nobody objected to.
