Can we grasp, understand and describe the experience of museum visitors? This study focuses on the visitor experience from an enactive perspective, i.e., that which makes sense from the point of view of visitors during their visit. The main results concern the method of investigation, which is innovative in the field of museum studies and provides a new perspective on the experience of visitors in museums. The thesis shows that an analysis of the visitor’s “course of experience” carried out by means of a subjective re situ interview allows us to describe and understand the basic units of the visitors’ experiences as well as the overall experience of the visit with precision, finesse, and depth. The actions and cognitive paths of visitors, which contribute to the construction of the knowledge, are also highlighted and we offer standard courses of experience during museum visits, which repeatedly contribute to the construction of knowledge.
