Taipei 101 — landmark skyscraper in Taipei

Design and structural features

The tower’s design draws on traditional Asian forms: the stacked segments resemble a stylized pagoda and invoke bamboo as a symbol of growth and resilience. Architect C.Y. Lee led the project, which used a reinforced concrete core and an exterior steel and glass curtain wall. Deep foundation piles anchor the building into bedrock to resist seismic forces and typhoon winds.

• Tuned mass damper: A large suspended steel and concrete pendulum near the top reduces sway during strong winds and earthquakes, improving occupant comfort.
• Elevators: High‑speed lifts connect the ground floor to the observatory in under a minute; the vertical transportation system was noted for its high speed at the time of opening.
• Energy and sustainability: The tower has been subject to upgrades to improve energy performance and has received recognized green building certification for operational improvements.

History and records

When it opened in 2004 Taipei 101 surpassed the Willis Tower in Chicago to become the world’s tallest completed building by structural height. It held that title until 2010, when a taller tower in the Middle East took the lead; for context see the earlier record holder Willis Tower and its successor Burj Khalifa in Dubai. Records associated with Taipei 101 have included measurements for roof height, highest occupied floor, and fast elevator speeds. The building’s specific rankings have changed as taller structures have been completed elsewhere.

Uses, observatory and public events

Taipei 101 houses corporate offices, a multi‑level shopping mall at its base, restaurants, and public observatories. An indoor observation deck and an outdoor viewing area offer panoramic views of Taipei. The tower is also a focal point for annual events, most famously the New Year’s fireworks and countdown celebrations that draw both locals and visitors; see notes on the building’s role in New Year's Eve festivities.

Notable distinctions and context

Beyond raw height, Taipei 101 is frequently cited for its engineering responses to a challenging climate of earthquakes and typhoons. Its tuned mass damper and robust structural systems are studied as examples in earthquake‑resistant design. The building contributed to Taipei’s skyline identity and to urban renewal in the Xinyi District; it is often referenced in travel guides and architectural overviews of Taipei and Taiwan. While later towers have exceeded Taipei 101 in absolute height, it remains notable for its combination of cultural symbolism, engineering innovation and public prominence.
