The term "Papal Residence" refers to the official residence of the Pope, the leader of the Roman Catholic Church. The most well-known Papal Residence is the Vatican City, specifically the Apostolic Palace, which serves as the Pope's home and the administrative center of the Church. In addition to the Apostolic Palace, the Pope may also reside in other locations, such as the Castel Gandolfo, a summer residence located outside Rome. These residences are significant not only for their religious importance but also for their historical and architectural value.
