The exhibition forms part of public dissemination from a hree-year research project addressing modern cultural heritage processes and remote presence funded by the Swedish National Heritage Board (Riksantikvarieämbetet). The project explores how public participation and remote presence may affect cultural heritage processes over time. Case studies include mediated museum extensions to Birka and Djurgården, where a public archaeological excavation was carried out in 2008 to investigate the remains and traces of the 1897 Stockholm Art and Industry fair. Interdisciplinary research collaboration between researchers at KTH Dept. Architecture (Charlie Gullström), Media Technology (Leif Handberg) and archaeologists at the Museum of National Antiquities, Stockholm (Fredrik Svanberg, Katty Hauptman-Wahlgren).
