Viking VR is a Virtual Reality exhibit through which viewers can experience the sights and sounds of a 9 th Century Viking encampment. Created as part of a major museum exhibition, the experience was developed by an interdisciplinary team consisting of artists, archaeologists, curators and researchers. In this paper, approaches to the design of authentic, informative and compelling VR experiences for Cultural Heritage contexts are discussed. We also explore issues surrounding interaction design for the long-term deployment of VR experiences in museums and discuss the challenges of VR authoring workflows for interdisciplinary teams.
