Cambridge Observatory

Cambridge Observatory is an astronomical observatory at the University of Cambridge in the East of England. It was established in 1823 and is now part of the site of the Institute of Astronomy. The old Observatory building houses the Institute of Astronomy Library which has a collection of modern and historical astronomical books.

There are a set of optical telescopes at the site on the Madingley Road in the west of Cambridge. By modern standards these are small, as well as being affected by light pollution. The 36-inch telescope was used for studies of stellar radial velocities until 2019, and the historic Northumberland and Thorrowgood telescopes are used as part of the public outreach activities of the Institute.

From 1990 to 1998, the Royal Greenwich Observatory was based in Cambridge in Greenwich House, just to the north of the Observatory.
