Once home to Queen Christina of Sweden, whose richly frescoed bedroom witnessed a stready stream of male and female lovers, 16th-century Palazzo Corsini was designed by Ferdinando Fuga, in grand Versailles style, and houses part of Italy's national art collection. The highlights include Caravaggio's mesmerising San Giovanni Battista (St John the Baptist), Guido Reni's unnerving Salome con la Testa di San Giovanni Battista (Salome with the Head of John the Baptist), and Fra Angelico's Corsini Triptych, plus works by Rubens, Poussin and Van Dyck.
