Angkor is one of the most important archaeological sites in South-East Asia. Angkor Archaeological Park contains the magnificent remains of the different capitals of the Khmer Empire, from the 9th to the 15th century. They include the famous Temple of Angkor Wat and, at Angkor Thom, the Bayon Temple with its countless sculptural decorations. Vibrant, bustling Phnom Penh is the heartbeat of Cambodia. This sprawling capital, spread out beside the banks of both the Tonlé Sap and Mekong Rivers, is a city of wide central boulevards and skinny back alleys where modern and old collide.
