REIMAGINING TRENT PARK – Home of The Secret Listeners




Follow the creation of an exciting  new national ‘living’ museum, opening in 2021.

As the former home of the Bevans and Sir Philip Sassoon, Trent Park was at the centre of some of the most defining moments of the 20th century…

But at the outbreak of the Second World War, it took on a role that would propel its importance to a level on a par with Bletchley Park. But no one would learn about it for 70 years… 


The house played a critical role in the ‘secret war’ against Nazi Germany. It was here that British Intelligence bugged the conversations of German prisoners-of-war, and from 1942 exclusively held Hitler’s Generals and high ranking officers. In a clever deception plan, whilst they enjoyed the luxurious stately rooms and roamed the gardens, their  conversations were secretly recorded from the basement by a team of secret listeners.

This site’s war-winning intelligence worked alongside Bletchley Park and other clandestine units to shorten the war and save lives.

This unique place in wartime espionage was set against the backdrop of an extraordinary  pre-war history. The pre-war years reveal an opulent life as a socialite’s retreat, where royalty such as a young Princess Elizabeth (later Elizabeth II) and the Prince of Wales (later the abdicated king, Edward VIII), politicians from David Lloyd George to Winston Churchill, and celebrities like Charlie Chaplin and Lawrence of Arabia revelled during the ownership of the enigmatic Sir Philip Sassoon.

The museum will be developed across the restored stately rooms on the ground floor and the atmospheric basement of the Grade II listed mansion house at Trent Park. Its future is assured after its new owners Berkeley Homes recognised the historical significance of the site and planning was granted for a museum to be run by the Trent Park Museum Trust.


The Trust is working closely with Berkeley Homes, the owners of this 50-acre Green Belt site, and is extremely grateful to the professional team at Berkeley for its dedication to the museum and commitment to deliver the highest quality redevelopment of this much-loved site. The Trust has a number of professional experts on board to realise the vision of something extraordinary for the nation, including the Prince’s Regeneration Trust which has been advising our team on the establishment of the Museum.
