Bletchley Park estate

The Bletchley Park estate was a country house estate near London that became famous for codebreaking during the Second World War. After a period of post-war neglect it became the site for the Bletchley Park Museum. The mansion was constructed during the years following 1883 for the financier and politician Herbert Leon in the Victorian Gothic, Tudor and Dutch Baroque styles, on the site of older buildings of the same name.

After the war it had various uses including as a teacher-training college and local GPO headquarters. By 1990 the huts in which the codebreakers worked were being considered for demolition and redevelopment. The Bletchley Park Trust was formed in February 1992 to save large portions of the site from development.
