The temples of Angkor, in Cambodia, built by the Khmer civilization, between 802 and 1220 AD, represent one of the most astonishing and enduring architectural achievements of mankind. The largest and the most well-preserved is Angkor Wat, built for King Suryavarman II in the early 12th century. It has become a symbol of Cambodia, appearing on its national flag. Angkor Wat combines two basic plans of Khmer temple architecture: the temple mountain and the galleried temples. The temple is admired for the grandeur and harmony of its architecture, its extensive bas reliefs and the numerous devatas adorning its walls.
