If you only have time for one art gallery in Rome, make it this one. Housing what’s often referred to as the ‘queen of all private art collections’, it boasts paintings by Caravaggio, Raphael and Titian, plus sensational sculptures by Bernini. Highlights abound, but look for Bernini’s Ratto di Proserpina (Rape of Proserpina) and Canova’s Venere vincitrice (Venus Victrix).
