Restoration is the activity of maintenance, recovery, repair and conservation of works of art, of cultural heritage and historical artifacts, whether they are pictorial elements (paintings on canvas, wooden panels, sculptures, frescoes), monuments, sculptures, manuscripts, buildings (masonry structure, decorated ceilings, decorated floors), reintegrating the compromised or deteriorated details and ensuring their preservation over time.
“Restoration must aim at re-establishing the potential unity of the work of art, provided that this is possible without committing an artistic or historical forgery, and without erasing any trace of the passage of the work of art over time”. Cesare Brandi
