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. Nevertheless, the 36-inch telescope continues to be used for studies of stellar radial velocities and the historic Northumberland and Thorrowgood telescopes are used as part of the public outreach activities of the Institute. Much more significant is the Mullard Radio Astronomy Observatory, built in 1957, a few kilometres southwest.

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