Angkor served as the seat of the Khmer empire that flourished from approximately the 9th century to the 15th century A.D. More precisely, the Angkorian period may be defined as the period from 802 A.D., when the Khmer Hindu monarch Jayavarman II declared himself the "universal monarch" and "god-king" of Cambodia, until 1431 A.D., when Thai invaders sacked the Khmer capital, causing its population to migrate south to the area of Phnom Penh.
The ruins of Angkor are located amid forests and farmland to the north of the Great Lake (Tonle Sap) and south of the Kulen Hills, near modern day Siem Reap (13°24'N, 103°51'E), and are a UNESCO World Heritage Site. The temples of the Angkor area number over one thousand, ranging in scale from nondescript piles of brick rubble scattered through rice fields to the magnificent Angkor Wat, said to be the world's largest single religious monument. Many of the temples at Angkor have been restored, and together they comprise the most significant site of Khmer architecture. Visitor numbers approach one million annually.
Described as the largest building serving so-called religious purposes. Looks more like a walled fortress than a temple, though. ;-)
Anybody up to model it?
