The group cave-temples in Dunguang, Gansu Province of north-western China offer an unparalleled display of grotto art of over a thousand years from the fourth century to the fourteenth century. They represent a microcosm of ancient and medieval civilizations, providing us with enormous opportunities of heritage experience and understanding. However, these grotto treasures are extremely fragile. Over the centuries they have been suffering from serious deterioration and damage due to human and natural causes, and in recent decades the ever-increasing visitor load has posed even greater threat to the murals. The emerging trend of using advanced technology in the preservation and the interpretation of the grotto art offers new possibilities of remote access and interpretation which shall enhance understanding and enjoyment of the cultural treasures. This dissertation sets out to examine such trend of digital interpretation of heritage in off-site scenarios. The research includes a background of the study, the significance of the Dunhuang Caves, the application of new technology, followed by a case study of re-presenting and interpreting one of the Dunhuang caves in Hong Kong. / published_or_final_version / Conservation / Master / Master of Science in Conservation
