The Papal Archives are the official repository of documents and records of the Pope and the Vatican. They contain a vast collection of historical materials, including letters, decrees, and other important documents that date back to the 8th century. These archives are crucial for understanding the history of the Catholic Church and its influence on global events. Access to the Papal Archives is limited, primarily to scholars and researchers who seek to study the Church's history. In 2020, the archives were opened to the public for documents related to the papacy of Pope Pius XII, which has sparked interest in the Church's role during World War II.
