The Digital Twin of the Panorama of the Battle of Murten: Notes on the Creation of the World’s Largest Image307

The Panorama of the Battle of Murten (Louis Braun, 1893/1894) is the only Swiss historical panorama not accessible to the public. As part of the celebration of the 550th anniversary of the Burgundian Wars in 2026, the Foundation for the Panorama of the Battle of Murten and the Laboratory for Experimental Museology at the Swiss Federal Institute of Technology have undertaken a project to digitize and valorize the original painting. The digitization phase has now been completed, producing the largest digital image of an artwork (1,600 gigapixels). This report details this achievement from a technical point of view, and highlights the new strategies for valorization offered by the digital twin. The project is part of an exploratory approach, going beyond standards in the cultural industries and enabling advances in data science research, but also in new museology. The new possibilities offered by ultra-highresolution images concern the fields of conservation, but above all the new paradigms of access to cultural heritage dealing with scientific imaging, large-scale visualization, humanities and public history.
