American rock climber Alex Honnold ascended the Taipei 101 skyscraper on Sunday without any ropes or protective equipment.

Cheers erupted from a street-level crowd as he reached the top of the spire of the 508-meter (1,667-foot) tower about 90 minutes after he started.

Wearing a red short-sleeve shirt, Honnold waved his arms back and forth over his head.

Honnold, known for his ropeless ascent up Yosemite National Park’s El Capitan, climbed up one corner of Taipei 101 using small L-shaped outcroppings as footholds.
