[3] For the word "Bang" is central Thai name for a populated place or settlement situated on the bank of the waterway.

[3] During the 19th century, around the King Rama V's reign, Bang O was considered a place for the lumber trade, as was Bang Pho on the opposite side of the Chao Phraya River, with the terrain being a bank sloping down to the river.

Therefore, Bang O was suitable as a place for mooring ships and loading and unloading goods.

[3] Those who received timber trade concessions from the government at that time were mostly foreign companies, such as Bombay Burmah and East Asiatic (modern EAC Invest A/S), etc.

[4] Once Bang O was the location of the residence of Chonlathee Thanthong, a renowned luk thung (Thai country song) composer.
