Siem Reap was only a village when the first French explorers in the 19th century rediscovered Angkor. With the transition of Angkor under the jurisdiction of the French in 1907, Siem Reap began to grow in the first wave of tourism. The Grand Hotel d’Angkor opened its doors in 1929, and the temples of Angkor remained one of the leading Asian sights until the late 1960s. In 1975 the population of Siem Reap (and other cities in Cambodia) was evicted by the Khmer Rouge into the countryside.
Because of the long civil war the city was in decline and slowly began to recover as a tourist center until the mid-1990s. Today, Siem Reap is undoubtedly Cambodia’s fastest growing city and serves as a small charming prelude to examination of Angkor temple complexes. Thanks to Siem Reap, Angkor has become a bustling tourist center with modern hotels and architectures. Despite strong international influence, Siem Reap and its people have retained much of the traditional appearance of the city and culture.
The Tuol Sleng Museum is an important part of the history of Khemr Rouge and can be an excellent tourist spot due to its historical significance. It is a former high school located in Phnom Penh was converted by the Khmer Rouge to a center of detention, torture and execution between 1975 and 1979. The school was secretly named as Security Prison 21 or S-21. Currently this school can be visited. It contains, besides the almost complete remains of buildings of torture and imprisonment, many objects of torture and interesting archives. It is also possible to watch a movie, the story of Hout Bophana. The Khmer Rouge S-21 enclosed all opponents to the regime, for any reason. Both young and older people were trapped. There were women, children, and sometimes entire families (including infants) of workers, of intellectuals, of ministers and diplomats in Cambodia, but also foreigners (Indians, Pakistanis, British, Americans, Canadians, Australians) The simple act of wearing glasses (including children) was sufficient to be considered intellectual and therefore the people were exterminated (Bowra, 1995).
