A Multidisciplinary Methodological Framework for the Enhancement of Underground Built Heritage Through Graphic Design: From Documentation to Interpretation

Often, research on the enhancement of heritage is limited to exhaustive geometric documentation of its elements. This is even more the case with Underground Built Heritage (UBH), where heritage information differs greatly from other types of heritage and is often so complex that many efforts focus on geometrically describing its three-dimensional volume and compiling heritage data. However, precisely because of its uniqueness, these actions are not always sufficient to understand underground heritage assets. This research proposes an itinerary of specific actions, an experimental methodology that not only focuses on the above, but also addresses the issue of UBH through sensory interpretation, using a taxonomy together with a graphic and plastic proposal of physical objects that can be handled and touched, allowing vision and touch to explore the tectonic qualities of these spaces, which are usually hidden or difficult to perceive due to inadequate lighting. The proposed workflow aims to be replicable in other research and applicable, either partially or fully, to other case studies of UBH.
