The aim of the Department of the Restoration and Preventive Conservation is to ensure the conservation of all the works in the Museu Nacional d'Art de Catalunya collections. The Department helps to guarantee the physical conservation of all the museum's holdings, including both works on exhibition and in storage, on deposit or on loan, whilst also seeking to delay as far as possible the ageing process that affects the materials that form the artworks. In addition, the Restoration and Preventive Conservation Department also studies the materials and the technical aspects of works with a view to providing scientific and technical assistance for art historians specialising in different periods, promoting dialogue and interdisciplinary studies.
