Well that and Notre Dame, The Eiffel Tower, The Louvre, Musee D'Orsay, The Pompidou Centre, The Picasso Museum, The Dali Museum, Place de la Concorde, Tuilleries Gardens, Champs Ellysees, Les Invalides, The Pantheon, The Opera House, The Catacombs, Pere Lachaise Cemetary, Jardins de Luxembourg, La Defense, The Arc du Triomph, Musee de la Mode, Saint Sulpice, Saint Michelle, Rue de Lappe, Moulin Rouge, Pigalle, The Crazy Horse, The Conciergerie...
