Preah Vihear Temple
In 1975, following the fall of the Lon Nol regime on 17 April the Khmer Rouge entered the capital Phnom Penh. But the final area held by the ill-fated Khmer Republic in any form would be the Preah Vihear Temple in these mountains. Khmer National Armed Forces occupied the place in late-April that year. They held on for a few weeks until the hill where the temple stands was finally taken by the Khmer Rouge on 22 May.
