In a feat of remarkable athleticism and nerve, American rock climber alex Honnold completed a free solo ascent of Taipei 101, Taiwan’s iconic skyscraper, on Sunday. The climb, broadcast live on Netflix wiht a 10-second delay, drew a global audience and highlights a growing trend of pushing the limits of human potential in extreme sports. Honnold’s ascent-without ropes or safety gear-comes nearly six years after his historic free solo of El Capitan, and underscores his reputation as one of the world’s moast daring athletes.
A daring free solo climb of Taipei 101, one of the world’s tallest skyscrapers, captivated onlookers Sunday, as American climber Alex Honnold scaled the 508-meter structure without ropes or safety gear. The feat highlights the growing popularity of extreme sports and the increasing willingness of athletes to push the boundaries of human capability, drawing international attention to Taiwan’s iconic landmark.
Honnold completed the ascent of the Taipei 101 in approximately 90 minutes, reaching the building’s spire. A crowd gathered below to witness the climb, cheering as he reached the top and raised his arms in celebration, wearing a red shirt against the backdrop of the city.
The climb, initially scheduled for Saturday, was postponed due to inclement weather. It was broadcast live on Netflix with a 10-second delay as a safety precaution, allowing producers to halt the feed in case of an accident.
Following the climb, Honnold revealed that his compensation from the streaming platform was a “embarrassingly small” amount compared to typical earnings in professional sports in the United States. He clarified to The New York Times that he wasn’t paid to scale the building itself, but for the spectacle. “If there wasn’t a show, I would do it for free,” he said.
The Taipei 101, with its 101 floors, is a prominent feature of the Taipei skyline. The most challenging section for climbers lies in the middle of the structure: the 64 levels comprised of the building’s distinctive “bamboo boxes.” These eight segments, each containing eight floors of steep, projecting walls, are interspersed with balconies where Honnold paused briefly during his ascent.
While not the first to ascend the building, Honnold is the first to do so without any protective equipment. French climber Alain Robert scaled the Taipei 101 in 2004 during the building’s inauguration, when it was the world’s tallest skyscraper.
The Taipei 101 primarily functions as a corporate tower, housing offices across three zones – low, mid, and high – and serving as the location for key financial institutions, including the Taiwan Stock Exchange.
The lower levels feature a shopping mall with luxury stores and restaurants, while observation decks on the 89th and 91st floors are popular tourist attractions.
Completed in 2003, the 508-meter tower weighs an estimated 700,000 tons and required an investment of approximately US$1.8 billion. It held the title of the world’s tallest building from 2004 to 2010, when it was surpassed by the Burj Khalifa in Dubai. Today, its spire places it as the third-tallest skyscraper globally, 56 meters taller than the Petronas Towers in Singapore, designed by Argentine architect César Pelli.
The building’s elevators are also noteworthy: a trip from the fifth to the 89th floor takes just 37 seconds, traveling at a speed of 1,014 meters per minute.
Taiwan is located in a seismically active region, and the Taipei 101 was engineered with this in mind. Its reinforced concrete structure combines rigidity and flexibility, enabling it to withstand earthquakes up to magnitude 7 and winds exceeding 450 km/h.
At the heart of the building’s technology is a tuned mass damper: a massive golden steel sphere located between the 82nd and 92nd floors. This device moves in a controlled manner to counteract the swaying of the tower, reducing its movement by up to 40%, according to The Washington Post.
The building’s size has fueled various theories, including one suggesting its weight reactivated an ancient geological fault. However, geologists dismiss this claim, noting that the excavated earth removed during construction weighed the same as the completed tower, resulting in no net change in pressure.
There have also been discussions regarding air safety, given the proximity of a nearby airport and the building’s height, drawing comparisons to the Twin Towers. In practice, the Taipei 101 is one of the most studied and monitored skyscrapers in the world.
