The Petronas Twin Towers (also known as the Petronas Towers), in Kuala Lumpur, Malaysia, were once the world's tallest buildings when measured from the level of the main entrance to the structural or architectural top.

The Petronas Twin Towers are the tallest twin towers in the world, and they lay claim to being the world's tallest high rise of the 20th century. Critics point out that this applies to only one of four height categories defined by the Council on Tall Buildings and Urban Habitat - although the three additional height categories were only introduced as the tower neared completion in 1996, as opposed to the original category which had been in use since 1969.

These towers, which were designed by architect César Pelli, were completed in 1998 and became the tallest buildings in the world on the date of completion. The 88-floor towers are constructed largely of reinforced concrete, with a steel and glass facade designed to resemble motifs found in Islamic art, a reflection of Malaysia's Muslim religion. 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.

The towers feature a skybridge (constructed by Kukdong Engineering & Construction) between the two towers on 41st and 42nd floors. The bridge is 170 m high and 58 m long. 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 passes (limited to around 1400 people per day, which usually run out before noon) must be obtained on a first-come, first-served basis. Passes are free. The skybridge is closed on Mondays.

The skybridge also acts as a safety device, so that in the event of a fire or other emergency in one tower, tenants can evacuate by crossing the skybridge to the other tower. However, the total evacuation triggered by a bomb hoax on September 12, 2001 showed that the bridge would not be useful if both towers need to be emptied simultaneously, and the capacity of the staircases was insufficient for such an event. Current plans thus call for the elevators to be used if both towers need to be evacuated, and a successful drill following the revised plan was conducted in 2005.
