American rock climber Alex Honnold ascended the Taipei 101 skyscraper on Sunday without any ropes or protective equipment.
Honnold climbed up one corner of Taipei 101 using small L-shaped outcroppings as footholds. Periodically, he had to maneuver around and clamber up the sides of large ornamental structures that jut out from the tower, pulling himself up with his bare hands.
