The palace is built directly atop the ancient substructures of Emperor Domitian’s villa, which spanned over 14 square kilometers.
The Barberini Gardens house a rare collection of ancient Roman cryptoporticus, underground galleries once used to support the imperial villa's structures.
The working farm on the grounds produces olive oil, honey, eggs, and dairy products that supply the Vatican City's administrative offices.
The palace observatory, known as the Vatican Observatory (Specola Vaticana), was relocated here in the 1930s due to light pollution in Rome.
Pope Francis decided not to reside in the Apostolic Palace, choosing to keep it as a public museum rather than a private retreat.
The Palazzo Pontificio serves as the historic summer residence of the popes, located in the town of Castel Gandolfo overlooking Lake Albano. Following a 2014 decree by Pope Francis, the palace and the sprawling Barberini Gardens were opened to the public as part of the Vatican Museums. The complex encompasses the Apostolic Palace, the terraced Barberini Gardens, and a working organic farm known as the Pontifical Villas. Visitors can view the Papal Apartments, which include the private chapel, the library, and the bedroom used by successive pontiffs. The site is built upon the ruins of the Roman Emperor Domitian's imperial villa, remnants of which are still visible within the gardens. The property covers approximately 55 hectares, merging Renaissance architectural elements with historical archaeological strata. Access is managed through the Vatican Museums' official ticketing system, allowing entry to both the palace and the landscaped gardens.

Wear comfortable, sturdy walking shoes, as the tour involves traversing significant distances across uneven gravel and paved paths in the gardens.
Book tickets well in advance through the official Vatican Museums website, as capacity for the apartment tours is strictly limited.
If possible, book the combined ticket that includes the electric shuttle tour of the gardens to save energy for the interior palace visit.
Do not attempt to walk from the train station to the palace without preparing for a steep uphill climb; consider local transport for the ascent.
Generally closed on Sundays; operating schedule can vary based on official Vatican protocols or private papal use.
Strict dress code: shoulders and knees must be covered. Silence is requested in the private chapel.
