Ban Pong (, ) is a district (amphoe) of Ratchaburi province, Thailand. It is in the northeast of the province. Geography Neighbouring districts are (from the north clockwise) Tha Muang and Tha Maka of Kanchanaburi province, Kamphaeng Saen and Mueang Nakhon Pathom of Nakhon Pathom province, and Photharam of Ratchaburi province. Ban Pong district is hilly in the western part of the district, while the eastern part is a flood plain with the Mae Klong River running through the city centre, connecting the city to the Gulf of Thailand. History The Mon people settled in the Ban Pong area about four centuries ago. The Mon communities have maintained some of their traditions and have built their own Buddhist temples. Later the town attracted numerous Chinese immigrants. Also many Lao Wiang communities settled in the Nong Kop subdistrict of rural Ban Pong. Two great fires occurred in Ban Pong, razing the town centre: one in 1936 and the other in 1954. The town was rebuilt in the square-grid design then fashionable, with a fountain to the south and a clock tower to the north. Camp Nong Pladuk During the Japanese-directed construction of the Burma Railway in World War II Nong Pladuk was the site of one of the Japanese POW camps where numerous British, Dutch and allied troops arrived. Camp Nong Pladuk was initially used as a transit camp from where the prisoners were transported or had to walk to work camps along the Burma Railway. Later Nong Pladuk was used a revalidation camp. During World War II, 23,289 British, 12,329 Dutch, 4,708 Australian, 482 American, and 7,030 undetermined soldiers passed through Camp Nong Pladuk.
