The Interior

The interiors of the towers highlight the Malaysian cultural inspiration to the design through traditional aspects such as fabricand carvings typical of the culture,

Specifically evident in the foyer of the entrance halls in the towers

A Multinational Collaboration

The construction of the Petronas Towers turned out to be a multinational effort

The structural design engineers worked out of New York City

The wind-tunnel consultants and elevator design engineers were from Canada

The inspiration of architect César Pelli is rooted in the tradition of the culture and the Islamic symbols including the geometric eight-pointed star floor design

Malaysia’s own ambition and aspiration. As evident in Pelli hoping the skybridge would symbolize a gateway to the future

Several scenes of popular bollywood film Don: The Chase Begins Again were filmed in Petronas towers and the skybridge

A quote by the building's main architect:

"According to Lao Tse, the reality of a hollow object is in the void and not in the walls that define it. He was speaking, of

course, of spiritual realities. These are the realities also of the Petronas Towers. The power of the void is increased and made

more explicit by the pedestrian bridge that ... with its supporting structure creates a portal to the sky ... a door to the infinite."

—César Pelli, architect (1995)
