Tourists have happily embraced the possibilities of interactivity and publication provided by social
media and Web 2.0. The last decade has seen a massive increase of digital content generated by tourists
online. This paper examines the digitalization of tourists’ heritage experience, analyses the impact of
social media and user generated content in the consumption of heritage sites, and discusses new forms
of technologically mediated authenticity in tourism. Netnography and a constructive approach have
been adopted for the examination of online communities and social networks. There are different
types of tourist generated content online. This study focuses on the review genre and examines a
purposive sample of data collected from Tripadvisor which, with over 30 million contributions, is the
largest online community focusing on tourism and travel. Through a systematic analysis of tourists’
narratives and socio-technical structures, this study assesses how technologies influence tourists’
heritage experience. The research findings provide insights into the role that tourists’ online reviews
play as mediators of the tourism experience and illustrate the features of an emerging virtual tourism
culture
