Bletchley Park
Bletchley Park is the home of British codebreaking and a birthplace of modern information technology. It played a major role in World War Two, producing secret intelligence which had a direct and profound influence on the outcome of the conflict. The site is now a museum and heritage attraction, open daily. The Bletchley Park Podcast brings you fascinating stories from Veterans, staff and volunteers on the significance and continued relevance of this site today.

In 1945, Britain celebrated VE Day in May and VJ Day in August, as the war - first in Europe and then the Far East - came to an end. For the staff of GC&CS and its larger worldwide network, this meant that the vital and exhausting work they'd been doing suddenly stopped. The lives of all of them had been changed forever, but each person's experience was different.

On 15 August 2025 the UK commemorated the 80th anniversary of VJ Day, the day on which the surrender of Japan and the end of World War Two was announced.
This was a significant moment at Bletchley Park as it meant the end of almost six years of non-stop codebreaking and intelligence work.

By late 1944, the tide had turned against the Japanese in south-east Asia, with the repulse of their attempted invasion of India. However, the multi-national Allied forces in Burma still faced enormous challenges if they were to retain the initiative, and push the enemy out of the country.

In 1943 there seemed to be few mysteries left unsolved for Bletchley Park. But by the middle of that year, whispers would be heard of new threats: the V-1 ‘flying bomb’ and V-2 rocket.
