Opening today at Hughenden Manor: a permanent exhibition on the secret wartime mapping activities that took place at the Buckinghamshire mansion during the Second World War.

In rooms never before opened to the public, the installation features original photographs, records and memories of personnel involved at the time.

In newly accessible spaces used by the mapmakers themselves, the interactive exhibits shed light on how Hillside played such a significant role in shaping the outcome of the war. […]

Codenamed ‘Hillside’, Hughenden played such a critical role supporting the pilots of nearby Bomber Command that it was on Hitler’s list of top targets.

Around 100 personnel were based here, drawing up the maps used for bombing missions during the war, including the ‘Dambusters’ raid and for targeting Hitler’s mountain retreat Eagle’s Nest. Skilled cartographers produced leading-edge maps from aerial photographs delivered by the RAF’s reconnaissance missions.

The BBC News story provides more detail: some 3,500 hand-drawn target maps were produced at Hughenden Manor during the War.
