Per
Preah Vihear — The pride of an empire, the cost of a disputed border.
« « The Temple is situated in territory under the sovereignty of Cambodia. » »— International Court of Justice, Judgment of June 15, 1962
Preah Vihear: A Disputed Treasure
Preah Vihear temple, dedicated to the god Shiva, was built between the 9th and 12th centuries, primarily under the reigns of Khmer kings Suryavarman I and Suryavarman II. Strategically perched on a rocky spur of the Dângrêk Mountains, it offers breathtaking views of the Cambodian plain. Its linear architecture and intricate bas-reliefs illustrate the zenith of Khmer art and its deep religious symbolism, making it a major site of the Khmer Empire.
The temple's status became a major point of contention between Cambodia and Thailand in the early 20th century, following the border delimitation by the Franco-Siamese Commission in 1907. Although the map appended to the treaty placed the temple on the Siamese side, the International Court of Justice ultimately ruled in favor of Cambodia in 1962, based on territorial sovereignty. Despite this decision, tensions and armed clashes have erupted sporadically, particularly after its inscription on the UNESCO World Heritage List in 2008, underscoring the site's geopolitical and nationalistic importance for both nations.
