UNESCO World Heritage



Till now, Cambodia has 5 cultural heritage sites. Apart from this, UNESCO also has separate programs called “Intangible Heritage of Humanity” and “Memory of the World.” In Cambodia, there are four of them respectively.

Cambodia is home to five UNESCO World Heritage Sites, each with deep cultural, historical, and memorial significance:


Cambodia’s UNESCO World Heritage Sites

1. Angkor

  • A sprawling archaeological complex in Siem Reap, dating from the 9th to 15th centuries. It includes over a thousand temples—most famously Angkor Wat, built in 1150 by King Suryavarman II, originally as a Hindu temple and later converted to Buddhist use. This site is a symbol of Khmer architecture and even features on Cambodia’s national flag

2. Preah Vihear Temple

  • An 11th-century Hindu sanctuary perched atop a cliff at 525 meters in the Dângrêk Mountains, dedicated to Shiva. Inscribed in 2008, Preah Vihear has been notably involved in territorial disputes with Thailand, which were settled in Cambodia’s favor by the International Court of Justice.

3. Sambor Prei Kuk (Temple Zone of Ancient Ishanapura)

  • An archaeological site from the late 6th to 7th century, located in Kampong Thom Province. It was the capital of the Chenla Kingdom and inscribed in 2017. Its pre-Angkorian ruins include numerous brick and sandstone temples, octagonal towers, and lion sculptures.

4. Koh Ker (Ancient Lingapura or Chok Gargyar)

  • A remote and mighty 10th-century temple complex, which briefly served as a Khmer capital. Nestled between the Kulen and Tbeng mountains, it includes temples, sanctuaries, inscriptions, and monuments. Koh Ker was just added to the UNESCO list in 2023.

5. Cambodian Memorial Sites: From Centres of Repression to Places of Peace and Reflection

  • This recent addition (July 2025) consists of three poignant sites connected to the Khmer Rouge genocide: the former M-13 Prison, the Tuol Sleng Genocide Museum (S-21), and the Choeung Ek Killing Fields. Their inclusion underscores Cambodia’s commitment to remembering and educating about this painful chapter in modern history.

Final Thoughts

Cambodia’s UNESCO sites span an incredible range—from the majestic temples of Angkor and the sacred heights of Preah Vihear, through the ancient roots of Sambor Prei Kuk and Koh Ker, to the solemn memorials of the Khmer Rouge era. Each embodies a distinct layer of Cambodia's layered heritage—from ancient civilizations to modern reconciliation.

UNESCO World Heritage of Cambodia

UNESCO World Heritage refers to sites registered on the World Heritage List. In November 1972, UNESCO adopted the "Convention Concerning the Protection of the World Cultural and Natural Heritage" in the General Conference during its seventeenth session. Under the Convention, the World Heritage committee established a World Heritage List that includes cultural and natural heritage with outstanding value whose conservation is recognized to be in the interest of all humanity.
