Tourism : Petronas Twin Tower





Tourism is travel for recreational, leisure or business purposes. The World Touris Organization defines tourists as people who "travel to and stay in places outside their usual environment for more than twenty-four (24) hours and not more than one consecutive year for leisure, business and other purposes not related to the exercise of an activity remunerated from within the place visited". Tourism has become a popular global leisure activity. In 2008, there were over 922 million international tourist arrivals, with a growth of 1.9% as compared to 2007. International tourism receipts grew to US$944 billion (euro 642 billion) in 2008, corresponding to an increase in real terms of 1.8% on 2007


Malaysia is rank in Top 15 most visited cities by international tourists in 2007.




The Petronas Twin Towers (Malay: Menara Berkembar Petronas) (also known as the Petronas Towers or just Twin Towers), in Kuala Lumpur, Malaysia are twin towers and were the world's tallest buildings before being surpassed by Taipei 101. However, the towers are still the tallest twin buildings in the world. They were the world's tallest buildings from 1998 to 2004 if measured from the level of the main entrance to the structural top, the original height reference used by the United States Council on Tall Buildings and Urban Habitat from 1969 (three additional height categories were introduced as the tower neared completion in 1996).



The Petronas Twin Towers were the tallest buildings in the world until Taipei 101 was built, as measured to the top of their structural components (spires, but not antennas). Spires are considered integral parts of the architectural design of buildings, to which changes would substantially change the appearance and design of the building, whereas antennas may be added or removed without such consequences. The Petronas Twin Towers remain the tallest twin buildings in the world.


The Willis Tower and the World Trade Center towers were each constructed with 110 occupied floors – 22 more than the Petronas Twin Towers’ 88 floors. The Willis Tower and the World Trade Center’s roofs and highest occupied floors substantially exceeded the height of the roof and highest floors of the Petronas Twin Towers. The Willis Tower’s tallest antenna is 75 m (246 ft) taller than the Petronas Twin Towers’ spires. However, in accordance to CTBUH regulations and guidelines, the antennas of the Willis Tower were not counted as part of its architectural features. Therefore, the Petronas Twin Towers exceed the official height of the Willis Tower by 10m, but the Willis Tower has more floors with occupied office space at a higher level.



This towers feature a skybridge 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. Visitors are only allowed on the 41st floor as the 42nd floor can only be used by the tenants of the building.


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 odd numbered floors and upper deck to even numbered floors. In order to access an even numbered floor from ground level, passengers are required to use an escalator to access the upper deck of the elevator.
