Paris has long been known around the world as the City of Light, though the name owes as much to its intellectual reputation in the Age of Enlightenment as to the electric lighting it introduced at the end of the 19th century. Fortunately, town planners in the intervening century have mostly taken the nickname literally. Transfigured by electric light, the landmarks of Paris now take on another dimension when evening falls. Drab obelisks turn to pointing fingers of light, the grey girders of the Eiffel Tower sparkle in gold and silver, and the glum boulevard around the Moulin Rouge becomes a flickering neon invitation. Who needs sleep, anyway?
