Now this is a truly sobering place to visit. This museum, located in downtown Kanchanaburi (and not next to the bridge, despite the misleading signs to another museum), features a bamboo hut that is built in the same style as the accommodation that the prisoners of war were housed in during the railway construction.
It features stories, eyewitness accounts, newspaper clippings, and as much information as possible regarding the construction of the railway and what life would have been like as you can absorb. Other than the below cemeteries, this was the place where the true horror of the railway construction became real for us.
