The National Museum of Cambodia houses one of the world's greatest collections of Khmer cultural material including sculpture, ceramics and ethnographic objects from the prehistoric, pre-Angkorian, Angkorian and post-Angkorian periods.
The main activities of the National Museum of Cambodia include exhibiting, safeguarding and promoting understanding of Cambodia’s cultural and artistic treasures. Keeping objects safe and working to ensure the repatriation of pieces stolen from Cambodia are important aspects of the museum’s work, particularly as looting and illicit export of cultural material are a continuing concern. In addition, the Museum strives to engage its visitors through its exhibitions and to fulfil its role as an integral part of the community. The Museum believes that Cambodia’s cultural heritage is of great value and can provide a source of pride and identity to the Cambodian people who have lost so much in recent decades. The availability of multilingual Museum tour guides and Publications, as well as the Museum’s public library, all serve to increase the accessibility of the collection both for local and international visitors.
