‘National Genocide Center’ is probably a newly-coined term to describe Cambodia’s Tuol Sleng Genocide Museum by travelers Matt and Debz. It’s also widely known as Security Prison 21 (S-21).

Our first full day in Phnom Penh gave us a chance to venture out in a Tuk Tuk to the infamous “Killing fields” or “National Genocide Center”. I’m not sure which sounds less inviting but it was a worthwhile visit to get more educated on an era of unimaginable horror for hundreds of thousands of Khmer.
