The airport is located in Racha Thewa in Bang Phli district, Samut Prakan Province, about 25 km east of downtown Bangkok. The nameSuvarnabhumi was chosen by King Bhumibol Adulyadej and refers to the golden kingdom hypothesised to have been located somewhere in Southeast Asia.
Designed by Helmut Jahn of Murphy/Jahn Architects, this airport has the world's tallest control tower (132.2 m), and the world's third largest single-building airport terminal (563,000 m²). Suvarnabhumi is one of the busiest airports in Asia and is also a major air cargo hub. The airport inherited the airport code BKK from Don Mueang after the older airport ceased international flights. A modern motorway connects the airport, Bangkok, and the heavily industrial Eastern Seaboard of Thailand, where most of the manufacturing for export takes place.
