Christine Kerrison worked as a project officer for Cambridgeshire County Council, designing services for people with learning disabilities. Based at Shire Hall, she remembers being taken down to a large underground bunker to be trained in the use of the new telephone system. Although the training session was fairly brief, she recalls how the bunker felt claustrophobic and creepy, with long corridors and no natural light.

Christine only visited the bunker once, and thinks she probably wouldn’t be able to find it again, but she remembers other members of staff using the showers there after cycling between meetings. Generally, she and her colleagues treated the out-dated bunker as a bit of a joke. Despite the issuing of the ‘Protect and Survive’ booklet in 1980, Christine felt less concerned then about nuclear threat than she had in the 1960s.
