Paris has wished the Eiffel Tower a happy birthday with an elaborate night-time laser show retracing the monument's 130-year history.
Earlier in the day on Wednesday, 1300 children were invited to a giant "snack time" beneath the tower known as the Iron Lady.
After nightfall, a 12-minute laser display began flashing across the facade in shows that will run until Friday night.
Professional climbers scaled the monument to mount the lights for the unprecedented show.
Around six million people ascend the tower every year, in addition to the crowds who just come to look at Gustave Eiffel's creation, designed for the 1889 World's Fair.
It was the world's tallest monument at the time, and thanks to strict urban planning rules, it still looms large above the Paris skyline.
The Eiffel Tower opened to the public for the first time on May 15 1889, several days after its inauguration at the fair.
