There is a plan in Paris to rebuild the Tuileries Palace. “No one has seen this handsome pile since it was torched by the Communards in 1871. For the past century and more the name ‘Tuileries’ has brought to mind not a building but a garden. Now, the French government is considering a project to put it back on the original site, opposite the Louvre, at an estimated cost of 300 million euros ($383 million). If the plan — which would be funded from private sources — goes ahead, it will by no means be unique. To a surprising extent, the monuments of Europe are not original, but reproduction.”
