Also in Kanchanaburi, near the Myanmar border, is the Bridge on the River Kwai. It is part of the death railway, constructed by the Japanese during WW2 through the use of POWs and Asian slave labour - it is said that there was one life lost for every sleeper laid on the track. Built in 1942 and within a year; the original was blown up by the allies in 1944. It's now a tourist destination where you can buy an unbelievable amount of tat. Worth a visit.
