Facts & Legends

A verified historical oddity: The "River Kwai" was actually called the Mae Klong until the 1957 film popularized the name; the Thai government eventually renamed a stretch of the river "Khwae Yai" to accommodate tourist expectations. A local legend in Sangkhla Buri concerns the Sunken Temple (Wat Sam Prasop); it is said that when the water level of the Vajiralongkorn Dam recedes to reveal the bell tower, it signals a period of spiritual renewal for the Mon people residing along the border.
