Bridge on the River Kwai
During World War II, Japanese used prisoners of war and impressed workers from various Asian nations to build a strategic railway from Thailand through to Burma. Over a hundred thousand people died, mainly due to malnutrition and lack of access to medical care.
This bridge (which is not the actual Bridge On the River Kwai, the subject of the famous 1957 U.S. movie starring Alec Guiness and William Holden) commemorates the suffering of the people who built the railway.
Covered buildings nearby contain photos and accounts (in English and Thai) of the project and the human toll it took.
Walking through here feels a bit like visiting the Vietnam War Memorial in Washington, DC. (those of you who have been there will know what I mean). I'm not saying that the Vietnam War and the Death Railway were similar so much as I'm just saying that both memorials seem sad to me. You get the feeling that a lot of people died who shouldn't have.
