In Paris, the Eiffel Tower went dark. In London, a kaleidoscope of famous sites switched off their lights, Tower Bridge, Big Ben, Piccadilly Circus, the London Eye. That scene was repeated over and over across the world on Saturday night: at Sydney's Opera House; at New Delhi's great arch; at Kuala Lumpur's Petronas Towers; at Edinburgh Castle in Scotland; at Brandenburg Gate in Berlin; at St. Basil's Cathedral in Moscow.
