Taipei 101: Learning to move with the wind

TAIPEI, Taiwan — The first thing one notices about Taipei 101 is its height. At 508 meters, it rises above the city’s financial district, its stacked sections narrowing toward the sky like bamboo. From almost anywhere in the surrounding streets, it is difficult to ignore.

The second thing is what the building represents.

Completed in 2004, Taipei 101 was once the tallest building in the world, a distinction it held until Dubai’s Burj Khalifa surpassed it in 2010.

Its design, by Taiwanese architect C.Y. Lee and his team, draws on traditional Chinese symbolism. The eight stacked sections recall bamboo, associated with strength, flexibility and growth. The number eight, considered auspicious in Chinese culture, carries its own associations with prosperity.

There is something deliberate about the way the building rises. It looks toward the future while carrying symbols of the past.

But Taipei is a city built with an awareness of what can happen when the ground moves. Taiwan lies along a seismically active region and is regularly exposed to typhoons. A building of this size cannot simply be designed to resist every force around it. It must accommodate some movement.

This is where Taipei 101 becomes particularly interesting.

The weight of staying upright

Suspended inside the tower, between the 87th and 92nd floors, is a 660-metric-ton steel sphere known as a tuned mass damper. Measuring 5.5 meters in diameter, the golden structure moves in response to the building’s sway, helping counteract motion caused by strong winds and seismic activity.

It is an unusual thing to find inside a skyscraper: a massive pendulum whose purpose is to keep another massive structure steady.

The engineering is largely invisible to people on the streets below. But for visitors who see the damper from the observatory, it offers a glimpse of the calculations behind the building’s apparent stillness.

Taipei 101 was never designed around the idea that a skyscraper should not move. It was designed around the understanding that it would.

The city below

From the 89th-floor observatory, roughly 382 meters above ground, Taipei takes on a different scale. Roads become narrow lines. Buildings lose their individual identities. Beyond the dense urban landscape, mountains frame the city.

The journey upward takes approximately 37 seconds, with high-speed elevators carrying visitors from the fifth floor to the observatory.

There are offices, restaurants and a shopping mall within the complex. The building is not merely something to look at or photograph. It remains part of the city’s commercial life, which was, after all, the reason for its construction.

The view from above is impressive. But the more revealing experience may be understanding what it takes to keep the tower functioning below.

After the record

The building has increasingly focused on sustainability through energy-efficient lighting, automated controls and low-emissivity glass designed to reduce heat entering the structure.

It received LEED Platinum certification for existing building operations and maintenance in 2011, followed by WELL Health-Safety Rating Platinum recognition in 2023. In 2025, it announced another LEED v5 Platinum achievement.

There are now taller towers. There will be others. The skyline is an unfinished competition, and height is a record that eventually belongs to someone else.

Taipei 101 remains.

Its significance lies partly in its engineering, partly in its symbolism, and partly in the particular conditions of the place where it stands. It is a building designed for a city that knows the ground can shift and the winds can turn.

At 508 meters, it rises above Taipei with the confidence of a monument. Somewhere inside it, the great golden sphere continues to move.

The building stands because it knows it cannot remain entirely still.
