Bletchley Park

Bletchley Park was a Ministry of Defence monitoring base where Rachel Jensen (TV: Remembrance of the Daleks) and Toshiko Sato's grandfather (TV: Greeks Bearing Gifts) worked in World War II.

Before her marriage to Edward Grainger, Eleanor Grainger worked at Bletchley, at first as a "glorified typist", then she received a minor promotion. She met George Tremayne there, who courted her for six months. (PROSE: Ancient Whispers)

The Sixth Doctor worked there for a couple of months and he met Constance Clarke there. (AUDIO: Criss-Cross)
