Devesham was an English village and the locale of a Space Defence Station. Its senior astronaut, Guy Crayford, tested the XK5 space freighter when it was launched from there, but contact with it was lost. Sarah Jane Smith covered the story.
The pub in the village was called Fleur-de-Lys.
Styggron created a replica of Devesham on Oseidon and populated it with android duplicates of the villagers and station personnel as part of the Kraals' plan to conquer Earth. It was destroyed shortly after the Fourth Doctor and Sarah Jane Smith arrived. At the real station, Styggron's androids began to take over, but were defeated by the Doctor. (DW: The Android Invasion)
