Physical heritage objects and assets are related to a vast amount of digital information of different kinds, which are challenging to be communicated to visitors in understandable and engaging ways. Yet recent technological advances promise new opportunities to more tightly merge the digital with the physical world. This paper therefore introduces the concept of “phygital heritage”, the integration of digital technology ‘into’ physical reality, as a potential medium for more enriched and playful communication of heritage values and qualities. We propose that phygital heritage should enable the exploitation of typical advantages of both digital and physical reality, and that distinct categories of phygital can be recognized based on: 1) the level of physical affordance; and 2) in how far the technology is integrated into the physical reality. The paper also opens the discussion about the potential challenges and concerns which future explorations, scientific research and real-world applications of phygital heritage probably will encounter.
