The Louvre at night is very beautiful. It's so much better to take photos there at night than during the day when it's swarming with tourists. At night it's more peaceful (well, slightly..if you can ignore all the Eiffel-Tower-keychain-selling-men), all the lights are on and I love the reflections on the little pools of water surrounding the pyramid. After taking photos of the area from every angle possible, I sat there one night for well over an hour just dreaming about the day I can finally move to Paris...
