Designed by Argentine-American architect César Pelli, the Petronas Towers were completed in 1998 and became the tallest buildings in the world on the date of completion. They were built on the site of Kuala Lumpur's race track. Because of the depth of the bedrock, the buildings were built on the world's deepest foundations. The 120-meter foundations were built by Bachy Soletanche, and required massive amounts of concrete
Spanning 17 acres below the building is the KLCC park with jogging and walking paths, a fountain with incorporated light show, wading pools, and a children's playground.
Suria KLCC is one of the largest shopping malls in Malaysia.
The towers feature a skybridge (constructed by Kukdong Engineering & Construction of South Korea) between the two towers on 41st and 42nd floors, which is the highest 2-story bridge in the world. The bridge is 170m above the ground and 58 m long, weighing 750 tons. The same floor is also known as the podium, since visitors desiring to go to higher levels have to change elevators here. The skybridge is open to all visitors, but free passes (limited to 1700 people per day) must be obtained on a first-come, first-served basis. The Skyway is closed on Mondays. Visitors are only allowed on the 41st floor as the 42nd floor can only be used by the tenants of the building.
