Our passionate curator takes you around the historic house exploring how the rooms were used over 70 years ago to carry out top-secret work as part of Operation Ultra.

You will have time after the tour to visit our exhibition displaying GI veterans’ memories and declassified files that reveal the importance of their round-the-clock, top-secret work, which helped defeat the Nazis.

Who would like this: Anyone interested in wartime history, especially Second World War and Bletchley Park.

Please dress for walking round a historic house, areas can be cooler and some old historic floors can be slightly uneven.

Please bring your ticket email to show to staff, so they can scan it. You can buy on the day as well if tickets are available.
