St Cedd's College

St. Cedd's College was a college in Cambridge University, a respected institute of higher education on Earth.

Professor Chronotis had residency at St. Cedd's College for some time, residing in his rooms--which were, unbeknownst to all, his TARDIS. (DW: Shada (TV story)

The Fourth Doctor and Romana travelled there to visit Professor Chronotis, in 1979, but were captured by a Time Scoop, and were unable to visit the professor--or even to recall that they had failed to do so. (DW: The Five Doctors, BFA:Shada (audio release))

The Eighth Doctor and Romana also visited St. Cedd's College to visit (once again) Professor Chronotis. (WC: Shada (webcast), BFA: Shada (audio release))

Chemistry student Chris Parsons studied at St. Cedd's College in the later 1970s.

Behind the Scenes
Douglas Adams re-used St. Cedd's, along with the character of Professor Chronotis, for his novel Dirk Gently's Holistic Detective Agency. The Professor in Dirk Gently, though, is not identified as a Time Lord, nor is his time machine identified as a TARDIS.
