Selangor is located on the west coast of peninsular Malaysia, south of the state of Perak and north of Negeri Sembilan.
In the heart of the state of Selangor is the Federal territory - the capital Kuala Lumpur and Putra Jaya. It is the state where the Kuala Lumpur International Airport (KLIA) is actually located (though often mentioned as located in KL). Though Selangor means "Abode of Serenity", a large part of Selangor is a built environment of cities, towns, highways and manufacturing centres - not exactly the quiet serenity perhaps. Selangor is also the richest state in Malaysia in terms of GDP.
Major Urban Centres
Shah Alam - is a town that was specifically designed to replace Kuala Lumpur, as the state capital. KL was handed over to the Federal Government on the 2nd of February 1974. The area, formerly called Sungai Reggam, became Shah Alam, the capital of Selangor.
Petaling Jaya, more commonly referred to as 'PJ', is the largest city in Selangor. In the 1950's due to rapid development and overcrowding in Kuala Lumpur, an extensive area of rubber plantations, outside KL was opened by the then British government for development as a satellite town.
