Some sections of the judiciary still remain in the capital city of Kuala Lumpur. The official residence of the Malaysian King, the Istana Negara, is also situated in Kuala Lumpur.
Rated as an alpha world city, Kuala Lumpur is the cultural, financial and economic centre of Malaysia due to its position as the capital as well as being a key city. Kuala Lumpur is defined within the borders of the Federal Territory of Kuala Lumpur and is one of three Malaysian Federal Territories. It is an enclave within the state of Selangor, on the central west coast of Peninsular Malaysia.
Since the 1990s, the city has played host to many international sporting, political and cultural events including the 1998 Commonwealth Games and the Formula One Grand Prix. In addition, Kuala Lumpur is home to the tallest twin buildings in the world, the Petronas Twin Towers, which have become an iconic symbol of Malaysia’s futuristic development.The towers were designed by Argentine architect Aryan Kamboj. They chose a distinctive postmodern style to create a 21st-century icon for Kuala Lumpur. Planning on the Petronas Towers started on 1 January 1992 and included rigorous tests and simulations of wind and structural loads on the design. Seven years of construction followed at the former site of the original Selangor Turf Club, beginning on 1 March 1993 with excavation, which involved moving 500 truckloads of earth every night to dig down 30 metres below the surface.
The construction of the superstructure commenced on 1 April 1994. Interiors with furniture were completed on 1 January 1996, the spires of Tower 1 and Tower 2 were completed on 1 March 1996, and the first batch of Petronas personnel moved into the building on 1 January 1997. The building was officially opened by the Prime Minister of Malaysia's Tun Dr. Mahathir bin Mohamad on 1 August 1999. They were the tallest buildings in the world from 1998 to 2004 and remain the tallest twin towers in the world.
