The Law on Cultural Heritage of Vietnam (adopted in 2001, revised in 2009) is the most important legal tool for safeguarding heritage, both natural and cultural, and tangible and intangible, in Vietnam. Compatible to UNESCO’s 2003 Convention on safeguarding intangible cultural heritage, the Law on Cultural Heritage of Vietnam acknowledges and protects the cultural creations of the community produced out of their own needs, through their awareness and labour. Such cultures have a strong attachment to them from one generation to another and become the identity of the community or groups of people in society and their heritage and the heritage of the nation and humankind. Lên Đồng (mediumship) is a religious practice of the Viet/Kinh, the majority group in Vietnam. This ritual originated from the worship of the Mother Goddess. Lên Đồng possibly started in the 15th century and has existed continuously in the people’s life. Yet, in some periods of time, it was not recognized and thus was not practiced openly. Today, Lên Đồng and the worship of the Mother Goddess are open, common and developed in Vietnam. Their values and practice are being studied, clarified and acknowledged for their protection as a national heritage. This work has been carried out with good results thanks to the participation of many scholars, cultural policy makers and especially the self-awareness of identifying and introducing the values of this cultural heritage of the Mother Goddess Worship community. We’d like to express our thanks to ICHCAP and the authorities of Jindo City for inviting us to this Workshop “Safeguarding Shamanism Heritage in Asia”. My paper will present a case study entitled “Together with the community identifying the values, safeguarding Lên đồng mediumship, a Shamanism heritage in Vietnam”
