The climb up the Taipei 101 skyscraper was completed without ropes or other safety equipment. It is the first time a free solo climber has scaled the building.
Down on the ground, cheers erupted from the assembled crowd as Honnold began his ascent of the 1,600-foot (508-meter) skyscraper, which is 101 stories high and was the world's tallest building when it was completed in 2004.
Honnold, 40, is best known as the only person to have free soloed El Capitan in Yosemite National Park in California. The feat was filmed in the documentary “Free Solo,” which won the Best Documentary Feature award at the 2018 Academy Awards.
