The emergence of new technologies in the heritage sector in recent years has opened the way for new relationships between the public and historical monuments and objects. Technologies that until recently were used for very specific needs, 3D scanning for example, are now used widely and allow museums and heritage managers to spread knowledge of their institutions and artefacts in unsuspected ways. Virtual reality is another of these advances, and allows completely immersive experiences, authentic journeys in time in which the viewer is surrounded by the past. Mappings, as in the case of #Taüll1123, involve stories being told in projected pictures, the magic thus seen to be running across the very walls of monuments. All these tools, combined with a narrative, and always following academic rigor in the preparation of the content, are examples of how far we can go in the dissemination of historical knowledge within the context of medieval heritage.
