Phnom Penh, the capital of Cambodia, offers an eclectic mix of Khmer culture, French colonial architecture and a deep dive into the gruesome past of Cambodia's Khmer Rouge regime. Don't miss the stunning Royal Palace of Cambodia and the infamous Killing fields under the Khmer Rouge regime.

A visit to the Choeung Ek Genocidal Centre, famously known as the Killing Fields, followed by a tour to the Tuol Sleng Genocide Museum, is an unsettling experience. The fact that one man, a political despot, Pol Pot, could steer a civil revolution to the point where almost three million innocent Cambodians were killed mercilessly by their own people within a span of four years, from 1975 to 1979, is truly baffling.
