Inside the Vatican Observatory: A Rare Glimpse

Castel Gandolfo: Vatican Observatory experience - Inside the Vatican Observatory: A Rare Glimpse

For the first time in nearly ninety years, visitors gain entry into the Vatican Observatory domes, which are fully operational. These domes include a major dome with an 8.5-meter diameter, equipped with a Visual Telescope ideal for stars and planets observation. Also accessible is a minor dome with an 8-meter diameter, housing the Double Astrograph used for sky surveys and star positioning.

These observatories were re-established in 1935 under Pope Pius XI, moving from the Vatican Gardens due to light pollution. The Vatican Observatory now hosts three telescopes and a spectrochemical laboratory, reflecting its ongoing commitment to astronomical research. The site has historically contributed to research on variable stars and other celestial phenomena.

Climb the Spiral Staircase to the Third Floor of the Palace

A notable highlight of this visit is the spiral staircase that leads to the third floor of the Papal Palace. Here, visitors can stand at the highest point of the building and enjoy a panoramic view of Lake Castel Gandolfo. This elevated perspective enhances the experience, allowing for great photo opportunities and a closer look at the surrounding landscape.

The staircase itself is part of the charm, offering a classic historic feel while providing access to the most scenic viewpoint of the entire tour. It’s a quick ascent, but the view from the third-floor terrace is memorable and worth the climb.
