All Paris, actually all Europe, was black in the 70's. You should see it now. They sand blasted the whole city and re gilded all the buildings and monuments. It's just down right stunning. London was even worse. Now it's completely different. I'm sure some of our forum Brit's will agree. No matter when, its a great way to see all the tourist attractions. Arc de Triumph, the Odelisk, La Place de la Concorde , Paris Opera, La Madelaine, Le Sacre Coure, Mont Matre, WOW!!!!
