In the 6th century, King Yasovarmamn I ( 889-900) began work on the original dedicated to Shisa as result of spiritual development, increased political prestige and economic growth was naturally reflected in the Temple undergoing more than 300 years of consultation with deal of remodeling under subsequent King Suryavarman II ( 1113 – 1150) this increased prestige naturally changed the original small sanctuary into one of the greatest Khmer temples of all times. This ranking was the result of the finest in situ carving that depicted the highest standards of unique Khmer architecture.
Under the Franco-Siamese Treaty of 1904 and 1907, the line of frontier between Cambodia and Thai along the Dongrak Mountains followed justice at the Hague officially found that the Preah Vihear Temple situated inside the Cambodia territory.
Preah Vihear Temple (Khmer: ប្រាសាទព្រះវិហារ Prasat Preah Vihear) is an ancient Hindu temple built during the period of the Khmer Empire, that is situated atop a 525-metre (1,722 ft) cliff in the Dângrêk Mountains, in the Preah Vihear province, Cambodia.
In 1962, following a lengthy dispute between Cambodia and Thailand over ownership, the International Court of Justice (ICJ) in The Hague ruled that the temple is in Cambodia.
Affording a view for many kilometers across a plain, Prasat Preah Vihear has the most spectacular setting of all the temples built during the six-century-long Khmer Empire. As a key edifice of the empire’s spiritual life, it was supported and modified by successive kings and so bears elements of several architectural styles.
Preah Vihear is unusual among Khmer temples in being constructed along a long north–south axis, rather than having the conventional rectangular plan with orientation toward the east. The temple gives its name to Cambodia’s Preah Vihear province, in which it is now located, as well as the Khao Phra Wihan National Park which borders it in Thailand’s Sisaket province, though it is no longer accessible from Thailand. On July 7, 2008, Preah Vihear was listed as a UNESCO World Heritage Site.
Preah Vihear Temple is located in a pleasant environment with an attractive countryside slightly east of the mid section of the Dongrek Mountains.
It is perched on the edge of a giant cliff, about 625 meters above sea level in Preah Vihear Province, Northern part of Cambodia, 625km from the capital city of Phnom Penh. It is also situated close to the Cambodia-Thai border.
