In this episode of Architecture Topics, we explore the full story behind the Petronas Towers in Kuala Lumpur, from their origins in late-20th-century Malaysia to the global controversy that reshaped how skyscrapers are measured.

Designed by César Pelli and completed in 1998, the Petronas Towers were declared the tallest buildings in the world, surpassing the Sears Tower in Chicago. That declaration sparked an intense international debate about architectural height, spires versus antennas, and what “tallest building” really means.

The controversy led to the formalization of global height standards by the Council on Tall Buildings and Urban Habitat, permanently changing how skyscrapers are compared and ranked.

Beyond records, this episode looks at the political ambition of 1990s Malaysia, the role of Petronas as a national symbol, the engineering challenges of building twin concrete towers on difficult ground, the meaning of the skybridge, and how the Asian Financial Crisis transformed the towers from symbols of growth into symbols of resilience.

A story about architecture, power, identity, and the moment when height became a global argument.
