Overview
- The Trent Park House of Secrets opened to the public after a press preview, with the museum director calling the launch a “momentous occasion” and visitor services including tickets, a café, and a shuttle already in operation.
- During World War II the house was turned into a covert listening centre where concealed microphones recorded conversations of senior German officers and teams in basement rooms transcribed and translated them.
- Those recordings produced actionable leads used by British intelligence, including material sent to Bletchley Park about Enigma, revelations of Luftwaffe navigation beams, and disclosures that flagged German ballistic‑missile development.
- The restoration recreates the 1930s state rooms and the basement listening stations, returns loaned Sassoon family items, and is presenting displays about roughly 3,000 recorded conversations and the roughly 40 mostly German‑speaking Jewish refugee listeners who worked at Trent Park.
- A local campaign and the Trent Park Museum Trust secured funding from Berkeley Homes, the National Lottery Heritage Fund and others to fund the project after delays caused by Covid-19, asbestos removal and rising costs, while parts of the former campus have been redeveloped for private housing under the site agreement.
