Petronas Twin Towers

The Petronas twin towers which rise up to 88 floors were built as an integral part of Kuala Lumpur City Centre (KLCC) Project in 1998.  Architects Ceaser Belli and associates designed the Petronas twin towers abiding by the country’s Islamic heritage and combining it with the modern.  The result is a graceful aesthetic steel and glass combination with a façade depicting motifs from Islamic art, the cross section of the buildings is in the form of the Rub-el –Hizb, another influence Islamic art. The Petronas towers follow the replicating geometric pattern and the interlinking sky bridge form an exotic gateway to the city.

Structure of the Petronas Twin Towers

  • Petronas Twin towers are made of high strength concrete, supported by 75 by 75 foot of concrete cores and surrounded by an outer ring of widely spaced super columns.  Each floor hence frees up 14,000 to 22,000 ft of column free office space.
  • The entire twin towers are covered with a curtain of glass and steel sun shades to block the intense sunlight.
  • A double decker elevator system with a sky lobby transfer point which can easily accommodate thousands of people who come daily.
  • At the base of the Petronas Twin Towers is the Suria KLCC, a humongous luxury retail outlet which also includes an art gallery, an underwater aquarium, a science centre and the Dewan Filharmonik Orchestra.
  • Spread across 17 acres below the Petronas twin towers is the KLCC Park with jogging paths, a fountain with light show, a wading pool, and a children’s playground.
  • The sky bridge is the highest two storey bridge in the world, and can slide in and out of the towers.
  • Today, Malaysia and Kuala Lumpur have become synonymous with the Petronas Twin towers.
