Located in the northern suburban city of Pakkret about 40 km from Bangkok's central business district, Mueang Thong Thani (Golden City) was established by real-estate developer Bangkok Land in 1989 as a self-contained satellite city with high-rise condominiums and an intended population of around 150,000 people.
The project languished in the mid-1990s with the East Asian financial crisis, but was revived in 1998 when Bangkok Land built Mueang Thong Thani Stadium as one of the three stadiums to host the 13th Asian Games. The stadium was expanded and renamed IMPACT Exhibition Centre in 1999. IMPACT Convention Center was built in 2000, while expansion of IMPACT Exhibition Centre was completed in 2003. The column-free IMPACT Challenger exhibition halls were completed in early 2006. Spanning 60,000 sq m, the IMPACT Challenger Halls are presently the world's biggest column-free exhibition halls.
