The fertile province of Chachoengsao (also known as Paet Rio) is situated just east of Bangkok. Its position along the Bang Pakong River has made it a prime agricultural hub of central Thailand. It is most famous for its production of mangos and the sacred Buddha image (Phra Phutthasothon) which is housed in Chachoengsao.
The name Chachoengsao, meaning “deep canal,” comes from Khmer. The alternate name Paet Rio literally translates to “eight stripes,” most likely a reference to the dried fish of the region which are sliced into eight stripes.
The province’s history dates back to the reign of King Phra Borom Tri Lokkanat, during the Ayutthaya period of Thai history. Most of the inhabitants live on the Bang Pakong River bank or along the canals. Located only 80 kilometers from Bangkok and stretching across 5,351 square kilometers, Chachoengsao is a developing tourist destination.
The local administration is divided into 10 districts and 1 sub-district: Amphoe Muang, Bang Khla, Bang Nam Prieo, Bang Pakong, Ban Pho, Phanom Sarakham, Sanam Chai Khet, Plaeng Yao, Ratchasan, Tha Takiap, and King Amphoe Khlong Khuean.
