Two months into his pontificate, Pope Leo XIV will leave Rome to spend two weeks on a pontifical estate in the lakeside town of Castel Gandolfo, 18 miles south of the city, and sometimes known as the “second Vatican City.”The pontiff will stay on the hilltop Vatican property “for a period of rest” from the afternoon of July 6 to the afternoon of July 20, the Vatican announced last month. Leo is scheduled to make public appearances from Castel Gandolfo on two Sundays, but otherwise, his public audiences and private audiences will be suspended during that time.Leo will also spend three days in Castel Gandolfo over the holiday weekend for the Solemnity of the Assumption of Mary Aug. 15-17. Pope Leo’s stay on the 135-acre pontifical estate, which includes multiple properties, extensive gardens, and a working farm, marks the continuation of a centuries-old papal tradition of summer rest.The Vatican Gardens at Castel Gandolfo.

The pool is also reportedly receiving a refresh in anticipation of Leo’s arrival.Previous popes lived during their retreats in the pontifical palace of the estate, which is situated on the border of the town of Castel Gandolfo and the gardens, opening up onto Liberty Square.But in 2016, Pope Francis converted the papal palace of Castel Gandolfo into a museum. Two years prior he had opened the gardens to visitors.The palace and gardens will remain open to the public during Leo’s stay, since he will be living in a different palazzo on the grounds — the Villa Barberini.The ‘second Vatican City’The papal ties to Castel Gandolfo date back to 1596; it became an official papal residence 30 years later. The Baroque architect Gian Lorenzo Bernini later added on to the property’s historic villa, first built by Emperor Domitian in the first century.The territory was conceded to the Holy See as an extraterritorial possession under the Lateran Pact of 1929. Since that time, Popes Pius XII, John XXIII, Paul VI, John Paul II, and Benedict XVI all spent at least part of the summers there, where they would pray the Sunday Angelus and mingle with the townspeople.The Vatican Gardens at Castel Gandolfo is located on the wooded slopes of the Alban Hills, overlooking the blue waters of a small volcanic crater lake.

And the quiet atmosphere and scenic gardens provided a restorative space for reading, writing, and taking walks — or in John Paul II’s case, a lap in the property’s swimming pool.For Benedict XVI, the villa was a favorite summer getaway during his pontificate. He also chose to spend some time there after resigning the papacy.“Since 1628, the popes have lived in Castel Gandolfo. Some more, some less, but their presence has been constant. This is a city accustomed to the daily life of the pope,” Mayor Alberto de Angelis told ACI Prensa, CNA’s Spanish-language news partner, last month.Pray with Pope Leo XIVPart of the papal presence in Castel Gandolfo is the opportunity to pray the Sunday Angelus with Leo. The public can see Pope Leo in Castel Gandolfo during the Angelus messages on July 13 and on July 20, which he will deliver from Liberty Square (Piazza della Libertà) in front of the pontifical palace.After nearly four weeks back at the Vatican, the pontiff will then return for three days to Castel Gandolfo, where he will recite the Angelus on Aug. 15 and Aug. 17.Visit Castel GandolfoTickets to visit the Papal Palace of Castel Gandolfo or its gardens (Borgo Laudato Si’) can be booked on the official website of the Vatican Museums for a weekend or weekday.The town of Castel Gandolfo, which sits above the volcanic Lake Albano, is also a pleasant spot for a stroll. The town is part of the area south of Rome known as the Castelli Romani.Pope Francis “did a lot for the city, opening the doors of the papal residence and the gardens... But now, Leo XIV will give back to the city its daily connection with the pope: the Angelus, the visits, the contact with the people. We want to experience all of that again,” Mayor de Angelis said.From Rome, Castel Gandolfo can be re
