Angkor, in Cambodia’s northern province of Siem Reap, is one of the most important archaeological sites of Southeast Asia. Stretching over some 400 square kilometres, including forested area, Angkor Archaeological Park contains the magnificent remains of several capitals of the Khmer Empire of the 9th to the 15th centuries, including the largest pre-industrial city in the world.
The word Angkor is derived from the Sanskrit nagara, meaning "city". The Angkorian period began in AD 802, when the Khmer Hindu monarch Jayavarman II declared himself a "universal monarch" and "god-king", until 1351, when Angkor first fell under Ayutthayan suzerainty, to 1431, when Ayutthaya put down a rebellion and sacked the Khmer capital, causing its population to migrate south to Longvek.
Angkor Archaeological Park was declared a UNESCO World Heritage site in 1992. At the same time, it was also placed on the List of World Heritage in Danger due to looting, a declining water table, and unsustainable tourism. UNESCO has now set up a wide-ranging programs to safeguard this symbolic site and its surroundings. The most famous things in Angkor are the Temple of Angkor Wat and, at Angkor Thom, the Bayon Temple with its countless sculptural decorations.
