Home of The Secret Listeners

Welcome to the official website of the Trent Park Museum where you can learn more about and follow the progress of the establishment of a full national museum which is well underway. The museum is not yet open to the public, with an anticipated opening in 2021.

Trent Park has a rich history from its earliest days as a Royal Hunting ground, but most pertinently during the Second World War. At the outbreak of 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 Museum’s primary focus will be the ‘secret war’ and the critical role that the mansion house and its beautiful grounds played in the Second World War. It was here that British Intelligence bugged the conversations of German prisoners-of-war, and from 1942 exclusively held the German Generals and high ranking German officers. In a clever deception plan, whilst the Generals 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. You can read a more about its unique role in our history section of the website.

This unique place in wartime espionage was set against the backdrop of an already extraordinary  pre-war history from the Bevan and Sassoon times – the secondary aspect of the museum. The pre-war years reveal an opulent life as a socialite’s retreat, where royalty such as a young Princess Elizabeth 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 agreed in its formal plans to Enfield Council to grant a lease to the Trent Park Museum Trust.

The Trust is working with relevant stakeholders, including 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.
