In short: Perched 525 meters above the Cambodian plains, Preah Vihear is an architectural marvel of the Khmer Empire. Yet, this ancient sanctuary is better known for a century-long border dispute between Cambodia and Thailand, leading to International Court of Justice rulings, military clashes, and a complex legacy of national identity.

Constructed over several centuries, Preah Vihear began as a Hindu temple dedicated to Shiva in the early 9th century. Unlike most Khmer temples that follow a rectangular east-facing plan, this complex stretches 800 meters along a north-south axis, serving as a stylized representation of Mount Meru. Its architecture evolved through various styles, including Koh Ker and Baphuon, with significant contributions during the reigns of Suryavarman I and Suryavarman II. The site eventually transitioned to Buddhist use as Hinduism declined in the region.

The modern conflict stems from a 1904 border agreement between Siam and French-ruled Cambodia, which intended to follow the Dângrêk mountain watershed. However, a 1907 French map deviated from this line, placing the temple in Cambodia. While Thailand long argued the map was invalid, the International Court of Justice ruled in 1962 that Thailand had acquiesced to the map over decades of silence. This decision awarded the temple to Cambodia, a ruling reaffirmed in 2013 after renewed tensions.

The site's history is marked by tragedy beyond territorial disputes. In 1979, the Thai government forcibly relocated thousands of Cambodian refugees to the area, pushing them over the steep cliff. The United Nations High Commissioner for Refugees estimated that 3,000 people died in this operation. In later years, the temple became a flashpoint for military skirmishes, with artillery fire causing damage to the structure as recently as 2011. Despite these conflicts, the site was inscribed as a UNESCO World Heritage Site in 2008, recognizing its outstanding universal value.
