Thai Border Peace Temple Thai - Japan At Three Pagodas Pass Editorial Image

This pass has been the main land route into western Thailand since ancient times, and is believed be the point at which Buddhist teachings reached the country from India in the 3rd century. During the Ayutthaya period in Thai history (14th-18th centuries), the pass was the main invasion route for the Burmese, but at times was also used against them by Siamese armies. The first of such was the Burmese invasion in 1548, which was part of the Burmese–Siamese War of 1548.nnDuring World War II, Japan built the infamous Death Railway (officially Taimen - Rensetsu Tetsudo) through the pass. There is a memorial to commemorate the thousands of Australian prisoners of war who (with other Allied prisoners and Asian civilians) died as forced labourers in the construction of the railway.nnThe region is home to several hill tribes, including Karens and Mons, who are unable or unwilling to obtain citizenship from either countries. Separatist armies have repeatedly tried to take seize of the pass from Burma, with the Mons in effective control until 1990, when Burmese troops regained it.
