Siam (Thai: สยาม, RTGS: Sayam) is an area in the Pathum Wan district of Bangkok. It is a de facto district/neighborhood that consists of roughly 43 acres (170,000 m²) of the Thai Royal Family's estate, of which 17 acres (69,000 m²) is the Sra Pathum Palace; the remaining 26 acres (110,000 m²), formerly home to the Siam Intercontinental Hotel and its royal gardens, are leased by the Crown Property Bureau to several vast, upscale shopping complexes that are located on either side of Rama I Road. Though no district of Bangkok legally exists by the name "Siam," local Thais refer to this area as such, and consider it to be the very heart of Bangkok.
