Angkor was the capital city of the Khmer Empire, which also recognized as Yasodharapura and flourished from approximately the 9th to 15th centuries. Angkor was a megacity supporting at least 0.1% of the global population during 1010–1220. The city houses the magnificent Angkor Wat, one of Cambodia’s popular tourist attractions.
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”, and lasted until the late 14th century, first falling under Ayutthayan suzerainty in 1351. A Khmer rebellion against Siamese authority resulted in the 1431 sacking of Angkor by Ayutthaya, causing its population to migrate south to Longvek.
The ruins of Angkor are located amid forests and farmland north of the Great Lake (Tonlé Sap) and south of the Kulen Hills, near modern-day Siem Reap city, in Siem Reap Province. 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 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. Visitors approach two million annually, and the entire expanse, including Angkor Wat and Angkor Thom is collectively protected as a UNESCO World Heritage Site. The popularity of the site among tourists presents multiple challenges to the preservation of the ruins.
In 2007, an international team of researchers using satellite photographs and other modern techniques concluded that Angkor had been the largest pre-industrial city in the world, with an elaborate infrastructure system connecting an urban sprawl of at least 1,000 square kilometres (390 sq mi) to the well-known temples at its core. Angkor is considered to be a “hydraulic city” because it had a complicated water management network, which was used for systematically stabilizing, storing, and dispersing water throughout the area. This network is believed to have been used for irrigation in order to offset the unpredictable monsoon season and to also support the increasing population.
Sambor Prei Kuk
Sambor Prei Kuk is an archaeological site in Cambodia located in Kampong Thom Province. The now ruined complex dates back to the Pre-Angkorian Chenla Kingdom (late 6th to 9th century), established by king Isanavarman I as central royal sanctuary and capital, known then as Isanapura. In 2017, Sambor Prei Kuk was declared as a UNESCO World Heritage Site.
Located on the Eastern bank of the Tonle Sap lake, close to the Sen River, the central part of Sambor Prei Kuk is divided into three main groups. Each group has a square layout surrounded by a brick wall. The structures of the overall archaeological area were constructed at variable times: the southern and north groups (7th century) by Isanavarman I, who is considered a possible founder of the city and the central group (later date).
The buildings of Sambor Prei Kuk are characteristic of the Pre-Angkorean period with a simple external plan. The principal material is brick, but sandstone is also used for certain structures. Architectural features include numerous prasats, octagonal towers, shiva lingams and yonis, ponds and reservoirs, and lion sculptures. Sambor Prei Kuk is located amidst mature sub-tropical forests with limited undergrowth. The area has been mined and could still contain unexploded ordnance.
