King Amphoe Bang Sao Thong is a subdistrict of Samut Prakan province in Thailand.

History

Bang Phli New Town (Thai Mueang Mai Bang Phli) was established between 1992 to 1993 as a residential area for high-income families. The area around the new town was then split off from Bang Phli and formed the new district.

The new town covers about 20,000 homes and can hold more than 100,000 people. There is also a complex of public facilities directly east of the town. Across the Bang Phli New Town Road east of these facilities are office buildings.

Administration

The subdistrict was created by splitting off three communes (tambon) from Amphoe Bang Phli. It is still subdivided into these three communes.
