The Eiffel Tower was dark for two nights, a symbol of Paris in mourning.
At 6 p.m. on Monday, it lit up again, brilliantly illuminated in blue, white and red as a show of national solidarity.
Per the request of Anne Hidalgo, the city's mayor, the tower will be lit with the colors of the French flag for three nights.
The city's motto, Fluctuar Nec Mergitur -- tossed but not sunk -- is being projected on the first-floor deck with a hashtag.
