The MuSA - Museum of Astronomical Instruments is located in the highest area of Naples: in Capodimonte.

The MuSA - Museum of Astronomical Instruments was born under the Bourbon reign at the end of the eighteenth century. The Museum is related to the Naples Observatory and houses a collection of astrological instruments . The instruments on display date back to the period between the sixteenth and twentieth centuries: photometers, calculation tools, telescopes and spectrographs .

The collection is full of prints and drawings that testify to the history of the Museum and the Observatory . Two instruments are of great interest : Reichenbach's meridian circle and the first edition of Copernicus' De Reveolutionibus Orbium Coelestium , both from the Farnese Collection.

The museum itinerary of the MuSA - Museum of Astronomical Instruments is composed of instruments, places, images and allows you to reconstruct a two-century journey to Naples. Today the museum is the most important astronomical observatory in the whole south.
