On your way through the Italian rooms , be sure to keep an eye peeled for Fra Angelico 's glowing and stupendous Annunciation , as well as for Antonello da Messina 's realistically detailed , intensely tragic Christ Sustained by an Angel , and Sandro Botticelli 's The Story of Nastagio Degli Onesti .
The Italian rooms can be quite exhausting to go through , due to all the precious art stored there .
