In the 1970s the Khmer Rouge regime executed many thousands of Cambodians. They transported their victims to what have since become known as the ‘Killing Fields’ where they were executed and buried unceremoniously in mass graves. One of these sites is a few kilometres outside Phnom Penh and can be visited on some of the Exodus holidays to Cambodia. Needless to say, a visit here is both moving and unsettling but for many, it’s important that the past is not forgotten, uncomfortable though it may be.
