Kanchanaburi_Province

Kanchanaburi (Thai: กาญจนบุรี, pronounced [kāːn.t͡ɕā.ná(ʔ).bū.rīː]) is the largest of the western provinces (changwat) of Thailand. The neighboring provinces are (clockwise, from the north) Tak, Uthai Thani, Suphan Buri, Nakhon Pathom, and Ratchaburi. In the west it borders Kayin State, Mon State, and the Tanintharyi Region of Myanmar.
Tourists are attracted by the history of its ancient civilization and the World War II Bridge over the River Kwai, originally spelt "Khwae" but officially changed to Kwai to accommodate the expectations of tourists.
