"Despite revolutions, sieges, World War I shelling, and World War II bombings, Paris still possesses a remarkable architectural unity. The city’s center looks much as it did in the late 19th century. But while the scars are not immediately visible, they are there, and the worst of them are self-inflicted: the product of a single hideous week in May 1871. This was the week that the Paris Commune died."
