Changsha, China - Austrian slack-line walker and climber Michael Kemeter scaled a 268-meter tower on Sunday in the city of Changsha in central China's Hunan Province.
Kemeter started its challenge on Sunday morning in bare hands without any protection measures.
The tower Beichen Times Square is located in the downtown area of Changshang. Its whole surface is the glass curtain wall. Only the metal strips on the wall are useful for the 23-year-old climber. The maximum span between the metal strips is 1.8 meters.
Kemeter's largest arms reach is 2.2 meters.
If succeeding, Kemeter will jump from the top of the building in parachute to challenge the extreme low-altitude parachuting.
Kemeter won the world fame in 2011 after he scaled the 152-meter cliffs in the Verdon National Park in France in bare hands.
