kanchanaburi was established by King Rama I as a defensive outpost against possible Burmese attacks in what is now Lat Ya Sub-district. In 1833, the town was moved about 16 km to the southeast along the river to its present site during the reign of King Rama III.where the Khwae Noi and Khwae Yai Rivers converge into the Mae Klong River, spans the northern banks of the river and is a popular spot for travelers. Its location at the edge of a mountain range keeps it much cooler than the other provinces of central Thailand. The city has two major commercial districts: the downtown area consists of a grid of several streets with office buildings, shop fronts, and a shopping mall; and the riverfront area businesses are mostly further west along River Kwai Road.
