Astronomical Observatory of Capodimonte
Named "the Vesuvius of Astronomy erupting gold" by a contemporary astronomer — and the instruments that earned that title are still here.

Joseph Bonaparte founded this in 1807, making it Naples' oldest scientific institution. The neoclassical building on Capodimonte hill — the first of its kind commissioned in the Kingdom of Naples — dates to 1812 and houses MuSA (Museum of Astronomical Instruments), an ancient library of rare books, and a public planetarium with a 40-cm telescope.
What to look for
- The Fraunhofer equatorial telescope, whose 17.5 cm objective was the largest ever built at the time it arrived
- MuSA's collection of ancient astronomical instruments
- The Ancient library's rare old books
The observatory sits on Capodimonte hill near the royal palace; MuSA and the planetarium are the public-facing highlights — check opening days before visiting.
