According to BBC News:
The Duchess of Cambridge has reopened a World War Two codebreaking centre, where her grandmother once worked.
The home of the Government Code and Cypher School in Buckinghamshire cost £8m to restore
The duchess also met Lady Marion Body, a former colleague of her paternal grandmother, Valerie Glassborow, who worked in Hut 16.
Ms Glassborow, who married the duchess’ grandfather Peter Middleton, was a civilian staff member at the centre…
The success of the centre’s codebreakers in breaking the German cypher systems Enigma and Lorenz, are credited with shortening the war by two years.
