Brera Astronomical Observatory
A Jesuit astronomer built it in 1764; the Austrian Empire later sent its staff to draw a meridian line across the floor of Milan Cathedral.

Founded by Roger Boscovich inside Palazzo Brera, the observatory passed from Jesuits to Habsburgs to the Italian state and is still a working research institution — about a hundred scientists now studying black holes, gamma-ray bursts, and X-ray optics for space missions. Astronomer Margherita Hack worked here from 1954 to 1964. The museum traces the full arc from founding instruments to those of the 1970s.
What to look for
- The 218mm Merz Equatorial Refracting Telescope, ordered in 1862 from German constructor Georg Merz — the observatory's first major upgrade under Italian rule
- Museum instruments spanning the observatory's opening in 1764 through the 1970s, showing how measurement tools evolved across Jesuit, Habsburg, and Italian eras
- The story of the Milan Cathedral meridian line, built by astronomers Giovanni Angelo Cesaris and Francesco Reggio at the request of Habsburg governor Count Giuseppe Di Wilczek in 1786
Located in Palazzo Brera in Milan's Brera district; operated jointly by INAF and the University of Milan.
