French climber Alain Robert, the French Spiderman, braved heights and high winds as he scaled the tallest building in the world.
Thousands of students looked on near the base of the Burj Khalifa tower in downtown Dubai late Monday, gathered for the 10th annual Education Without Borders conference.
Robert began what would be a roughly six-hour climb around 6 p.m., local time and reached the top of the structure shortly after midnight.
The climber has scaled 85 giant structures around the globe including many of the world's tallest structures, most of which he has scaled using only his bare hands and climbing shoes.
For this climb he used a rope and harness on Monday's ascent to comply with organizers' requirements.
Here's a look at the climb, plus a look at some of the other buildings and landmarks Robert's has tackled over the years
