Chiang Rak (Thai: เชียงราก, pronounced [tɕʰīaŋ raːk̚˥]) is a neighbourhood in the Bangkok Metropolitan Region outskirts that covers from the northern part of Pathum Thani Province to the southern part of Phra Nakhon Si Ayutthaya Province.
[1] [2] Originally, the Chao Phraya River that ran through Chiang Rak used to be more winding and hindered navigation than today.
In 1608, King Songtham of Ayutthaya ordered the construction of a canal bypassing a loop of the Chao Phraya River to shorten travel time.
[4] At present, Chiang Rak field has a large area of 43,994 rais (17,388 acres), covering an area from the northern part of Pathum Thani up till Sing Buri, Chai Nat, and Nakhon Sawan Provinces.
[5] Historically, on February 23, 1949, just a few days before the Palace Rebellion, Chiang Rak was used as an actual armed manoeuvre by the army until it was big news.
