The concept of accessibility has been examined by the scientific community in various fields such as education, health care, social inclusion, disabilities, transport, and tourism. Regarding heritage, the European Commission’s efforts toward accessible cultural heritage are highlighted, along with the use of digitisation and modelling technologies for complex heritage shapes. Thus, this chapter explores relevant scientific research into the accessibility of digital heritage models that represent the assets’ real condition, that is, as-is or as-built models produced using advanced digitisation and modelling technologies. The study emphasises the importance of both physical and semantic aspects of heritage conservation and the need for public awareness and cooperation toward the aimed accessibility. The methodology addresses the search for publications in Scopus and Web of Science and their filtering based on inclusion and exclusion criteria to ensure documents related to the accessibility of deformed digital heritage models are considered. The research concludes that creating accessible deformed digital heritage models is crucial for inclusion and participation from the public and stakeholders, and while some studies achieve accurate as-built geometries and accessibility, there is room for improvement
