The Petronas Twin Towers is a sky-piercing cultural landmark in Kuala Lumpur, which was, until 2004, the world's tallest twin structures. Its architecture is Islamic-inspired and the buildings are home to the corporate headquarters of the Petroliam Nasional Berhad, among other offices. Visitors can experience some of the best views in Kuala Lumpur by walking on the Skybridge and visiting the viewing point on the 86th floor.
