Discover a hidden room at the Palazzo Barberini in Rome

Up for a little treasure-hunting in Rome? Look for the hidden gem of the Palazzo Barberini in the palace's attic: the boudoir bedroom of Principessa Cornelia Costanza Barberini and her Colonna prince, created in 1728, is nearly unchanged from the wedding night. The low-hanging rooms are festooned in silk hangings, Japanese porcelains, and an antique baby carriage.
