Discover the Vatican Observatory at Castel Gandolfo

Unlock a unique opportunity to visit one of the world’s most historic astronomical sites: the Vatican Observatory inside the Papal Palace of Castel Gandolfo. For the first time in nearly ninety years, visitors are invited to explore the landmark domes that have shaped the study of the skies.

Inside, discover the Visual Telescope, a mainstay tool for observing constellations, planets and celestial events. Adjacent is the minor dome, featuring the historic Double Astrograph, instrumental in mapping stars and capturing photographic surveys of the night sky.

  • View cutting-edge astronomical equipment within the authentic working environment of Vatican scientists

  • Experience the atmosphere of research spaces used in significant scientific discoveries
