Castel Gandolfo: Vatican Observatory experience
Discover the secrets of the astronomical observatories housed within the Papal Palace of Castel Gandolfo. Explore the third floor of the palace and take in the breathtaking views of Lake Albano from the panoramic terrace.
For the first time in nearly ninety years since their construction, the astronomical domes of the Papal Palace of Castel Gandolfo are opening their doors to visitors. These fully functional observatories are two treasures of the Vatican Observatory: the "major dome," with a diameter of 8.5 meters, equipped with a Visual Telescope for observing stars and planets; and the "minor dome," with a diameter of 8 meters, featuring the Double Astrograph, used for photographic surveys of the sky and mapping star positions.
Access includes a spiral staircase leading to the third floor of the Papal Palace, at the highest point of the panoramic terrace, offering an extraordinary view of Lake Albano. It was Pope Pius XI who inaugurated the new headquarters of the Vatican Observatory on September 29, 1935, as the observatory was relocated from the villa built by Leo XIII in the Vatican Gardens, due to the increasing light pollution in the city.
The Astronomical Observatory was thus refounded and entrusted to the Jesuits, who equipped it with three new telescopes and an astrophysical laboratory for spectrochemical analysis. Among the most significant research programs of that era was a groundbreaking study on variable stars.
