Cambodia, in Southeast Asia, is famous for the Angkor Wat temple complex, a UNESCO World Heritage site and one of the largest religious monuments in the world. Phnom Penh, the capital, is a city of contrasts, with both colonial architecture and modern development. Cambodia has a dark recent history with the Khmer Rouge, but it's now a country on the path to recovery and growth, with tourism playing a vital role. The Tonle Sap Lake supports one of the world's largest freshwater fisheries, integral to the local economy.
