The story of landmines in Cambodia is told via the life of Aki Ra, founder, who was suppressed into the Khmer Rouge Army as a child soldier, and spent his youth fighting in the wars that ravaged his country for nearly 35 years. He established the Museum in 1997. After years of fighting he returned to the villages in which he planted thousands of mines and began removing them, by hand, and defusing them with homemade tools.
From the Landmine Museum web page:
The Cambodian Landmine Museum Relief Facility (CLMMRF) is more than a museum. It is also a home that provides education and support for dozens of at-risk youth and landmine affected children. Many children who are part of this family suffered overwhelming hardships. The Cambodian Landmine Museum Relief Facility was created so that it might serve as a place of healing for bodies, hearts and minds. We believe that love, support and education will help secure a better opportunity for the children who live here.
