Résumé en anglais
The exponential growth of social media platforms over the last decade has brought digitalculture and public participation to the fore in the field of heritage. Initially, social media promised to be
a panacea for democracy; enabling global communities to use digital technologies to engage with WorldHeritage properties. However, the reality has turned out to be much more complex and nuanced:
challenging established national narratives; potentially infringing on copyright; blurring notions ofcommunities and audiences; and revealing the entanglement of tangible and intangible forms of cultural
heritage.World Heritage is increasingly mediated by the digital sphere. In 2013 the Sydney Opera House had a
global online community of 128 million. These digital engagements outnumber in-person visits 16:1 andhave been estimated to have an economic value of $59 million AuD (Deloitte, 2013). Using the Sydney
Opera House as a case study, the paper describes public forms of participation with this place viaplatforms such as YouTube, Pinterest, Wikipedia, Facebook and Flickr. Then it reflects on their
implications for the World Heritage program’s strategic objectives of ‘increasing public awarenessthrough communication’ and ‘enhancing the role of communities’ in its implementation. There is a
growing imperative to evaluate the digital engagements of global online communities, especially whenmany of these ‘visitors’ will likely never physically set foot in the Sydney Opera House itself.
