The artworks are not on display either because under restoration or because on loan to temporary exhibitions. When specified, the dates always refer to the time frame of exhibits. Be careful: due to necessary controls to be done before they are moved, artworks may be not on display starting from some weeks before the exhibit's opening date. For the same reason, once back, there may be a further delay before they are on view again due to necessary conservators' check-ups. The lists are updated every month.
