Thousands of new bulbs made the enduring symbol of the City of Light twinkle again in Paris, June 21, 2003. Almost two years after wear-and-tear darkened the Eiffel Tower's lighting system. The 20,000 new lights on the tower recreate a glittering display originally meant to show off one of the world's most visited tourist sites on the night of the Millennium. The tower will be engulfed in twinkling lights for 10 minutes at the start of every hour from dusk until one or two each morning for the next decade.
