The room features a series of frescoes by Luca Ferrotti, the artist who painted the canvases in the Il Passito Room. The room was designed to be a whispering gallery. If you stand beside one of the columns, you can whisper something and a person on the other side of the forty-two-foot-wide room will be able to hear you perfectly. Whispering galleries were deliberately built into some castles so that conversations could be overheard from a distance.
