Fodor's Expert Review Palazzo Apostolico di Castel Gandolfo
For centuries, the Apostolic Palace of Castel Gandolfo was the summer retreat of popes, who kept the papal villa and extensive grounds completely private. Luckily for tourists, Pope Francis decided that he was too busy to use it and had it opened to the public. Inside you can view the Gallery of Pontifical Portraits, ceremonial garments, and the imposing papal throne in the Sala degli Svizzeri. The private area of the palace with the pope's bedchamber, his library, study, and offices are also open to visitors.
