The course acquaints students with the main historical and cultural steps in the restoration of artistic artefacts from the 15th to the 21st century, initiating them towards a methodological approach and critical tools necessary for the study of specific sources and the analysis of restoration solutions adopted in different periods and contexts. Together with the lectures, visits and conferences form in the student primary competences for interaction with the various professional figures with whom the art historian dealing with restoration and conservation must interact.
