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


Historic England recognises Trent Park House as being of national and international significance on a level with Bletchley Park.

Born out of a large-scale public campaign to save the House, the Trust (established in 2016) is working to deliver the highest quality redevelopment of this much-loved site. Our vision is to open one of London’s grandest houses to the public and reveal the incredible story of the Secret Listeners that has remained hidden in the house for over 70 years.

The Trust is currently trying to secure the funds needed to deliver the project with an aim of opening in 2025.
