The Petronas Towers, is also known as the Petronas Twin Towers. (In Malay word they call it Menara Petronas, or Menara Berkembar Petronas), so they are the twin skyscrapers in Kuala Lumpur, Malaysia. According to the Council on Tall Buildings and Urban Habitat (CTBUH)'s official definition and ranking, they were the tallest buildings in the world from year 1998 to 2004 and remain the tallest twin towers in the world. The buildings are a landmark of Kuala Lumpur, along with nearby Kuala Lumpur Tower.
Soaring to a height of 451.9 metres, the 88-storey twin structure is Kuala Lumpur's crown jewel. Majestic by day and dazzling at night, the PETRONAS Twin Towers is inspired by Tun Mahathir Mohamad's vision for Malaysia to be a global player or icon. Together with master architect Cesar Pelli, the international twin tower icon powerfully captures the nation's ambitions and aspirations.
Go visit Malaysia and experience first the PETRONAS Twin Towers. Begin your tour with interactive displays that showcase the journey, from idea to completion. Scale 170 metres in an elevator with a futuristic edge. The doors will open at the Skybridge, a connecting structure between the towers and the world's highest 2-storey bridge. Ascend even higher to level 86, where the story of Malaysia's vision unfolds amid breathtaking views of Kuala Lumpur. Then wrap up your visit with exquisite souvenirs at the gift shop.

KLCC Park View
Spanning 17 acres (6.9 ha) 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.

The towers feature a double decker skybridge connecting the two towers on the 41st and 42nd floors, which is the highest 2-story bridge in the world. It is not attached to the main structure, but is instead designed to slide in and out of the towers to prevent it from breaking, as the towers sway several feet in towards and away from each other during high winds. It also provides some structural support to the towers in these occasions. The bridge is 170 m (558 ft) above the ground and 58 m (190 ft) long, weighing 750 tons. The same floor is also known as the podium, since visitors going to higher levels have to change elevators here.
The skybridge is open to all visitors, but tickets are limited to about 1000 people per day, and must be obtained on a first-come, first-served basis. Initially, the visit was free but in 2010, the tickets started being sold by Petronas. Visitors can choose to opt for package one which is just a visit to the skybridge or go for package two to go to the skybridge and all the way to level 86. Visitors are only allowed on the 41st floor as the 42nd floor can only be used by the tenants of the building.
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. The total evacuation triggered by a bomb hoax on 12 September 2001 (the day after the September 11 attacks destroyed the twin towers of the World Trade Center in New York City) showed that the bridge would not be useful if both towers need to be emptied simultaneously, as the capacity of the staircases was insufficient for such an event. Plans thus call for the lifts to be used if both towers need to be evacuated, and a successful drill following the revised plan was conducted in 2005.
There is a two hinged arch that supports the skybridge with arch legs, each 51 metres (167 ft) long, that are bolted to level 29 of each of the towers. After being constructed on the ground, the skybridge was lifted into place on the towers over a period of three days in July 1995 but instead of being directly connected to the towers, the skybridge can shift or slide in and out of them to counterbalance any effect from the wind. Residing on the 41st and 42nd floors, the skybridge connects a conference room, an executive dining room and a prayer room.
Lift system
The main bank of Otis Lifts is located in the centre of each tower. All main lifts are double-decker with the lower deck of the lift taking passengers to even-numbered floors and upper deck to odd-numbered floors. To reach an odd-numbered floor from ground level, passengers must take an escalator to the upper deck of the lift.
There are 29 double-deck passenger elevators, but there are different sets that service certain floors of the towers, specifically two sets of six of these double-deck passenger elevators to floors 1–23 and 1–37 respectively. Another set of 5 passenger lifts transport passengers to the 41st and 42nd floors where they can switch lifts to reach the upper zones of the buildings, each double-deck passenger lift with the capacity of 52 passengers or, 26 passengers per deck. There are also 6 heavy-duty elevators for utility.
From the ground floor, there are three groups of lifts. The "short haul" group of 6 lifts take passengers to floors between level 2/3 and level 16/17. The "mid haul" group of six lifts take passengers to floors between level 18/19 and level 37/38. There is also a set of shuttle lifts that take passengers directly to levels 41/42. To get to levels above 41/42, passengers must take the shuttle lifts, then change to lifts to the upper floors. These connecting lifts are directly above the lifts that serve levels 2 to 38. The pattern now repeats with the upper levels, one set serving levels 43/44 to 57/58 and one set serving levels 59/60 to levels 73/74.
Apart from this main bank of lifts, there are a series of "connecting" lifts to take people between the groups. Unlike the main lifts, these are not the double-decker type. Two lifts are provided to take people from levels 37/38 to levels 41/42 (levels 39 and 40 are not accessible as office space). This spares someone in the lower half of the building from having to go back to the ground floor to go to the upper half of the building.
The lifts contain a number of safety features. It is possible to evacuate people from a lift stuck between floors by manually driving one of the adjacent lifts next to it and opening a panel in the wall. It is then possible for people in the stuck lift to walk between lift cars. During an evacuation of the buildings, only the shuttle lift is allowed to be used, as there are only doors at levels G/1 and levels 41/42; therefore should there be a fire in the lower half of the building, this enclosed shaft would remain unaffected. Firefighter lifts are also provided in case of emergency.
