Castel Gandolfo
Castel Gandolfo sits on the rim of an ancient volcanic crater, 426 metres above the Tyrrhenian coast, with Lake Albano filling the caldera below. For centuries this small town's identity has been inseparable from the Apostolic Palace at its centre — a 135-acre complex of villas, gardens, an observatory and working farmland, all under Vatican sovereignty since 1608.
The palace opened to the public in 2016, and since 2025 Pope Leo XIV has been returning to Villa Barberini for summer stays — so the town is, quietly, a papal residence again. Come for the Bernini church on the main piazza, the 55-hectare gardens that spill down toward Albano, and the long views over a lake that Romans were already engineering in 398 BC.
💛 What travellers fall for
Regulars tend to arrive early, before the tour groups reach the garden gates, and stay for a slow lunch on Piazza della Libertà with the lake visible at the end of every side street. The Emissario tunnel — a kilometre and a half of hand-cut rock from the fourth century BC — gets skipped by most visitors and rewards the ones who don't.

How Castel Gandolfo came to be
The ground beneath Castel Gandolfo was already imperial before it was papal. Emperor Domitian built his summer villa here between 81 and 96 AD, designed by the architect Rabirius across 14 square kilometres of crater rim. A Genoese family, the Gandolfi, raised a medieval castle on the same hill around 1200; it passed to the Savelli, who eventually surrendered it to the Vatican in 1596 as payment of a debt. Pope Urban VIII arrived on May 10, 1626 — the first pope to spend time here — and commissioned Carlo Maderno to convert the old castle into a proper palace.
Bernini completed the gardens of Villa Barberini in 1635 and designed the Collegiate Church of San Tommaso da Villanova for Pope Alexander VII in the 1660s. The palace stood empty from 1870 until the Lateran Treaty of 1929 confirmed its extraterritorial status. During World War II, Pope Pius XII opened the grounds to refugees; 12,000 people arrived from January 1944. Pope Francis converted the main building into a museum in 2016, and Pope Leo XIV became the first pope to resume summer residence here in 2025.

When to go
Summers are warm and drier than Rome, with the altitude and lake breeze making afternoons noticeably more bearable than in the city below. Winters are mild but can bring fog that settles over the crater; spring and October offer the clearest light and the least crowded paths.
