Trent Park Museum trustees with the Deputy Mayor of Enfield and local MP Bambos Charalambous


Opening Summer 2026, Trent Park House of Secrets in London is a new museum which will reveal the incredible story of the WWII ‘Secret Listeners’ - a story which has remained hidden for over 70 years.

Following the meticulous restoration of one of London’s grandest houses, visitors will journey through magnificently restored and furnished rooms that were the backdrop to Sir Philip Sassoon’s socialite and political world, where he hosted some of the most influential statesmen, journalists, royalty and politicians in the 1930s.

Following Sassoon’s death in 1939, Trent Park House began its second chapter as a wartime surveillance centre. The new museum will unveil the extraordinary story of the ‘Secret Listeners’ – intelligence operators hidden in the basement – whose eavesdropping of senior German prisoners led to some of the most important intelligence breakthroughs of WWII.

Born out of a large-scale public campaign to save the House, the Trent Park Trust (established in 2016) is working to deliver the highest quality redevelopment of this much-loved site.

This is an astonishing story of espionage, courage and creative deception which has remained untold until now.
