Main image

The Brera Astronomical Observatory (Osservatorio Astronomico di Brera) is a historic observatory in Milan, Italy, established in 1764 and housed in the Palazzo Brera. It combines an ongoing research role with a preserved collection of historical instruments and archives.

The observatory was created in the mid-18th century as part of the scientific and cultural institutions gathered at Palazzo Brera. Over the 19th and 20th centuries it served both practical astronomical research and cartographic/geodetic work, and its historical instruments and archives reflect that long institutional history.

Situated in Milan’s Brera district, the observatory sits within the Palazzo Brera cultural complex in central Milan, within easy walking distance of the Pinacoteca di Brera and other central landmarks.

  • Founding date: Founded in 1764, it is one of Italy's older astronomical observatories and is now part of national astronomical research networks.
  • Visiting: Located within the Brera cultural complex in central Milan, public access to the observatory and its collections is limited and often arranged through guided visits or special events.
